@inproceedings{noauthororeditor, abstract = {High main memory consumption is a significant cost factor for in-memory database systems. Tiering, i.e., placing parts of the data on memory or storage devices other than DRAM, reduces the main memory footprint. A controlled data placement can assign rarely accessed data to slow devices while frequently used data remains on fast devices, such as main memory, to maintain acceptable query latencies. We present an automatic data placement decision system for the in-memory database Hyrise. The system organizes the memory and storage devices in a tierless pool, with no fixed device class categorization or performance order. The system supports data placement use cases, such as minimizing end-to-end query latencies and making cost-optimal purchase recommendations in cloud environments. In this paper, we introduce an efficient calibration process to derive cost models for various storage devices. To determine data placements, we introduce a linear programming-based approach, which yields optimal configurations, and an efficient heuristic. With a set of main memory and SSD devices, we can reduce the main memory consumption for base table data of the TPC-DS benchmark by 74 percent when accepting a workload latency increase of 52 percent. In a comparison of data placement algorithms and cost models, we find that simplistic algorithms (e.g., greedy algorithms) can present viable alternatives to optimal linear programming algorithms, especially under cost prediction inaccuracies.}, author = {Hurdelhey, Ben and Weisgut, Marcel and Boissier, Martin}, booktitle = {Datenbanksysteme für Business, Technologie und Web, BTW}, keywords = {mboissierselected myown}, pages = {47-70}, publisher = {Gesellschaft für Informatik e.V.}, title = {Workload-Driven Data Placement for Tierless In-Memory Database Systems}, year = 2023 }

However, collaboration around DevOps artifacts has yet to receive detailed research attention. We apply the sociological concept of Boundary Objects to describe and evaluate the specific software engineering artifacts that enable a cross-disciplinary understanding. Using this focus, we investigate how different DevOps stakeholders can collaborate efficiently using common artifacts. We performed a multiple case study and conducted twelve semi-structured interviews with DevOps practitioners in nine companies. We elicited participants’ collaboration practices, focusing on the coordination of stakeholders and the use of engineering artifacts as a means of translation. This paper presents a consolidated overview of four categories of DevOps Boundary Objects and eleven stakeholder groups relevant to DevOps. To help practitioners assess cross-disciplinary knowledge management strategies, we detail how DevOps Boundary Objects contribute to four areas of DevOps knowledge and propose derived dimensions to evaluate their use.}, author = {Matthies, Christoph and Heinrich, Robert and Wohlrab, Rebekka}, booktitle = {Proceedings of the 27th International Conference on Evaluation and Assessment in Software Engineering}, keywords = {devops}, month = {jun}, publisher = {ACM}, title = {Investigating Software Engineering Artifacts in {DevOps} Through the Lens of Boundary Objects}, year = 2023 }

But even in the presence of these advantages, most in-memory database systems use data encoding only conservatively as the negative impact on runtime performance can be severe. Real-world systems with large parts being infrequently accessed and cost efficiency constraints in cloud environments require solutions that automatically and efficiently select encoding techniques, including heavy-weight compression. In this paper, we introduce workload-driven approaches to automatically determine memory budget-constrained encoding configurations using greedy heuristics and linear programming. We show for TPC-H, TPC-DS, and the Join Order Benchmark that optimized encoding configurations can reduce the main memory footprint significantly without a loss in runtime performance over state-of-the-art dictionary encoding. To yield robust selections, we extend the linear programming-based approach to incorporate query runtime constraints and mitigate unexpected performance regressions.}, author = {Boissier, Martin}, booktitle = {Proceedings of the VLDB Endowment}, keywords = {adm epic mboissierselected myown}, number = 4, pages = {780-793}, title = {Robust and Budget-Constrained Encoding Configurations for In-Memory Database Systems}, volume = 15, year = 2022 }

@inproceedings{richly2022budgetconscious, abstract = {Based on the performance requirements of modern spatio-temporal data mining applications, in-memory database systems are often used to store and process the data. To efficiently utilize the scarce DRAM capacities, modern database systems support various tuning possibilities to reduce the memory footprint (e.g., data compression) or increase performance (e.g., additional indexes). However, the selection of cost and performance balancing configurations is challenging due to the vast number of possible setups consisting of mutually dependent individual decisions.   In this paper, we introduce a novel approach to jointly optimize the compression, sorting, indexing, and tiering configuration for spatio-temporal workloads. Further, we consider horizontal data partitioning, which enables the independent application of different tuning options on a fine-grained level. We propose different linear programming (LP) models addressing cost dependencies at different levels of accuracy to compute optimized tuning configurations for a given workload and memory budgets. To yield maintainable and robust configurations, we extend our LP-based approach to incorporate reconfiguration costs as well as a worst-case optimization for potential workload scenarios. Further, we demonstrate on a real-world dataset that our models allow to significantly reduce the memory footprint with equal performance or increase the performance with equal memory size compared to existing tuning heuristics.}, author = {Richly, Keven and Schlosser, Rainer and Boissier, Martin}, booktitle = {Proceedings of the VLDB Endowment}, keywords = {adm ddds hyrise mboissierselected myown}, pages = {4079-4092}, title = {Budget-Conscious Fine-Grained Configuration Optimization for Spatio-Temporal Applications}, volume = {15 (13)}, year = 2022 }

We switched our on-site courses to remote setups without detailed knowledge of what tools, techniques, and methods would work in different teaching contexts.

However, university courses featuring practical software development projects present unique challenges regarding remote learning, as effective student collaboration is vital. In these courses, students tackle situations in the project and their team meetings that would also occur in real software projects experienced in industry settings. In this paper, we share our experiences on how we successfully adapted our software engineering project course to a remote setup, which challenges we observed in student teams and how they can be mitigated, and what (surprisingly) worked better than expected. Finally, we propose improvements that we expect will be beneficial not only for future remote-only but also for hybrid or on-site courses.}, author = {Matthies, Christoph and Teusner, Ralf and Perscheid, Michael}, booktitle = {Proceedings of the 55th Hawaii International Conference on System Sciences}, keywords = {teaching}, publisher = {Hawaii International Conference on System Sciences}, title = {Challenges (and Opportunities!) of a Remote Agile Software Engineering Project Course During {COVID}-19}, year = 2022 }

Especially in cloud scenarios with thousands of database deployments, determining optimized database configurations in an automated fashion is of increasing importance for database providers. At the same time, due to increased system complexity, it becomes more challenging to identify well-performing configurations. Therefore, research interest in autonomous or self-driving database systems has increased enormously in recent years. Such systems promise both performance improvements and cost reductions. In the literature, various fully or partially autonomous optimization mechanisms exist that optimize single aspects, e.g., index selection. However, database administrators and developers often distrust autonomous approaches, and there is a lack of practical experimentation opportunities that could create a better understanding. Moreover, the interplay of different autonomous mechanisms under complex workloads remains an open question. The presented cockpit enables an interactive assessment of the impact of autonomous components for database systems by comparing (autonomous) systems with different configurations side by side. Thereby, the cockpit enables users to build trust in autonomous solutions by experimenting with such technologies and observing their effects in practice.}, author = {Kossmann, Jan and Boissier, Martin and Dubrawski, Alexander and Heseding, Fabian and Mandel, Caterina and Pigorsch, Udo and Schneider, Max and Schniese, Til and Sobhani, Mona and Tsayun, Petr and Wille, Katharina and Perscheid, Michael and Uflacker, Matthias and Plattner, Hasso}, booktitle = {37th IEEE International Conference on Data Engineering, ICDE}, keywords = {adm autonomous database hyrise in-memory_database mboissierselected myown self-driving self-managing}, pages = {2685-2688}, title = {A Cockpit for the Development and Evaluation of Autonomous Database Systems}, year = 2021 }

In recent years, various integer compression techniques have been proposed that focus on sequential encoding and decoding and exploit modern CPUs' vectorization capabilities. Interestingly, another dominant access pattern in databases systems has seen little attention: random access decoding. In this paper, we compare end-to-end database performance for various integer compression codecs on three recent CPU architectures. Our evaluation suggests that random access performance is often more relevant than vectorization capabilities for sequential accesses. Before integrating selected encodings in the database core, we benchmarked seven libraries in an exhaustive standalone comparison. We integrated the most promising techniques into the relational in-memory database system Hyrise and evaluated their performance for TPC-H, TPC-DS, and the Join Order Benchmark on three different CPU architectures. Our results emphasize the importance of random access decoding. Compared to state-of-the-art dictionary encoding in TPC-H, alternatives allow reducing memory consumption of integer columns by up to 53 % while improving runtime performance by 5 % on an Intel CPU and over 16 % on an Apple M1.}, author = {Heinzl, Linus and Hurdelhey, Ben and Boissier, Martin and Perscheid, Michael and Plattner, Hasso}, booktitle = {International Workshop on Accelerating Analytics and Data Management Systems Using Modern Processor and Storage Architectures, ADMS@VLDB}, keywords = {mboissierselected myown}, month = 8, title = {Evaluating Lightweight Integer Compression Algorithms in Column-Oriented In-Memory DBMS}, year = 2021 }

This work describes an approach to tackle this issue by providing a dedicated tool, which is closing this gap between MOOC platforms and transcription and translation tools and offering a simple workflow that can easily be handled by users with a less technical background.

@phdthesis{teusner2021situational, abstract = {Massive Open Online Courses (MOOCs) open up new opportunities to learn a wide variety of skills online and are thus well suited for individual education, especially where proffcient teachers are not available locally. At the same time, modern society is undergoing a digital transformation, requiring the training of large numbers of current and future employees. Abstract thinking, logical reasoning, and the need to formulate instructions for computers are becoming increasingly relevant. A holistic way to train these skills is to learn how to program. Programming, in addition to being a mental discipline, is also considered a craft, and practical training is required to achieve mastery. In order to effectively convey programming skills in MOOCs, practical exercises are incorporated into the course curriculum to offer students the necessary hands-on experience to reach an in-depth understanding of the programming concepts presented. Our preliminary analysis showed that while being an integral and rewarding part of courses, practical exercises bear the risk of overburdening students who are struggling with conceptual misunderstandings and unknown syntax. In this thesis, we develop, implement, and evaluate different interventions with the aim to improve the learning experience, sustainability, and success of online programming courses. Data from four programming MOOCs, with a total of over 60,000 participants, are employed to determine criteria for practical programming exercises best suited for a given audience. Based on over five million executions and scoring runs from students' task submissions, we deduce exercise difficulties, students' patterns in approaching the exercises, and potential flaws in exercise descriptions as well as preparatory videos. The primary issue in online learning is that students face a social gap caused by their isolated physical situation. Each individual student usually learns alone in front of a computer and suffers from the absence of a pre-determined time structure as provided in traditional school classes. Furthermore, online learning usually presses students into a one-size-fits-all curriculum, which presents the same content to all students, regardless of their individual needs and learning styles. Any means of a personalization of content or individual feedback regarding problems they encounter are mostly ruled out by the discrepancy between the number of learners and the number of instructors. This results in a high demand for self-motivation and determination of MOOC participants. Social distance exists between individual students as well as between students and course instructors. It decreases engagement and poses a threat to learning success. Within this research, we approach the identified issues within MOOCs and suggest scalable technical solutions, improving social interaction and balancing content difficulty. Our contributions include situational interventions, approaches for personalizing educational content as well as concepts for fostering collaborative problem-solving. With these approaches, we reduce counterproductive struggles and create a universal improvement for future programming MOOCs. We evaluate our approaches and methods in detail to improve programming courses for students as well as instructors and to advance the state of knowledge in online education. Data gathered from our experiments show that receiving peer feedback on one's programming problems improves overall course scores by up to 17%. Merely the act of phrasing a question about one's problem improved overall scores by about 14%. The rate of students reaching out for help was significantly improved by situational just-in-time interventions. Request for Comment interventions increased the share of students asking for help by up to 158%. Data from our four MOOCs further provide detailed insight into the learning behavior of students. We outline additional significant findings with regard to student behavior and demographic factors. Our approaches, the technical infrastructure, the numerous educational resources developed, and the data collected provide a solid foundation for future research.}, author = {Teusner, Ralf}, keywords = {MOOC collaboration intervention peer-feedback programming}, month = {may}, title = {Situational Interventions and Peer Feedback in Massive Open Online Courses}, year = 2021 }

As DRAM capacities are limited and expensive, modern database systems apply various configuration optimizations (e.g., compression) to reduce the memory footprint. The selection of cost and performance balancing configurations is challenging due to the vast amount of possible setups consisting of mutually dependent individual decisions. In this paper, we present a linear programming approach to determine fine-grained configuration decisions for spatio-temporal workloads. By dividing the data into partitions of fixed size, we can apply the compression, sorting, and index selections on a fine-grained level to reflect spatio-temporal access patterns. Our approach jointly optimizes these configurations to maximize performance under a given memory budget. We demonstrate on a real-world dataset that models specifically optimized for spatio-temporal data characteristics allow us to reduce the memory footprint (up to 60% by equal performance) and increase the performance (up to 80% by equal memory size) compared to established rule-based heuristics.}, author = {Richly, Keven and Schlosser, Rainer and Boissier, Martin}, booktitle = {37th IEEE International Conference on Data Engineering (ICDE)}, keywords = {adm ddds epic mboissierselected myown}, pages = {1901-1906}, title = {Joint Index, Sorting, and Compression Optimization for Memory-Efficient Spatio-Temporal Data Management}, year = 2021 }

@inproceedings{hesse2021insert, abstract = {Message brokers see widespread adoption in modern IT landscapes, with Apache Kafka being one of the most employed platforms. These systems feature well-defined APIs for use and configuration and present flexible solutions for various data storage scenarios. Their ability to scale horizontally enables users to adapt to growing data volumes and changing environments. However, one of the main challenges concerning message brokers is the danger of them becoming a bottleneck within an IT architecture. To prevent this, knowledge about the amount of data a message broker using a specific configuration can handle needs to be available. In this paper, we propose a monitoring architecture for message brokers and similar Java Virtual Machine-based systems. We present a comprehensive performance analysis of the popular Apache Kafka platform using our approach. As part of the benchmark, we study selected data ingestion scenarios with respect to their maximum data ingestion rates. The results show that we can achieve an ingestion rate of about 420,000 messages/second on the used commodity hardware and with the developed data sender tool.}, author = {Hesse, Guenter and Matthies, Christoph and Uflacker, Matthias}, booktitle = {IEEE International Conference on Parallel and Distributed Systems (ICPADS)}, keywords = {esb imported kafka}, pages = {641-648}, title = {How Fast Can We Insert?

These data are analyzed to detect biomarkers that can be of prognostic or diagnostic use. Traditionally, biomarker detection for gene expression data is the task of gene selection. The vast number of genes is reduced to a few relevant ones that achieve the best performance for the respective use case. Traditional approaches select genes based on their statistical significance in the data set. This results in issues of robustness, redundancy and true biological relevance of the selected genes. Integrative analyses typically address these shortcomings by integrating multiple data artifacts from the same objects, e.g. gene expression and methylation data. When only gene expression data are available, integrative analyses instead use curated information on biological processes from public knowledge bases. With knowledge bases providing an ever-increasing amount of curated biological knowledge, such prior knowledge approaches become more powerful. This paper provides a thorough overview on the status quo of biomarker detection on gene expression data with prior biological knowledge. We discuss current shortcomings of traditional approaches, review recent external knowledge bases, provide a classification and qualitative comparison of existing prior knowledge approaches and discuss open challenges for this kind of gene selection.}, author = {Perscheid, Cindy}, journal = {Briefings in Bioinformatics}, keywords = {biomarker_detection cp geneselection}, publisher = {Oxford University Press}, title = {Integrative Biomarker Detection on High-Dimensional Gene Expression Data Sets: A Survey on Prior Knowledge Approaches}, year = 2020 }

In this research, we investigate the perceptions of Agile development practices and their usage in Scrum software development teams. Although perceptions collected through surveys of 42 participating students did not evolve significantly over time, our analyses show that the Scrum role significantly impacted participants' views of employed development practices. We find that using the version control system according to Agile ideas was consistently rated most related to the values of the Agile Manifesto. Furthermore, we investigate how common software development artifacts can be used to gain insights into team behavior and present the development data measurements we employed. We show that we can reliably detect well-defined Agile practices, such Test-Driven Development, in this data and that usage of these practices coincided with participants' self-assessments.}, address = {Bonn}, author = {Matthies, Christoph and Huegle, Johannes and Dürschmid, Tobias and Teusner, Ralf}, booktitle = {Software Engineering 2020}, editor = {Felderer, Michael and Hasselbring, Wilhelm and Rabiser, Rick and Jung, Reiner}, keywords = {imported}, pages = {73-74}, publisher = {Gesellschaft für Informatik e.V.}, title = {Attitudes, Beliefs, and Development Data Concerning Agile Software Development Practices}, year = 2020 }

These activities mostly rely on the collected perceptions of team members.

Knowing the impact of such optimizations helps in developing optimizers as well as in interpreting TPC-H results across database systems. This paper provides a systematic analysis of choke points and their optimizations. It complements previous work on TPC-H choke points by providing a quantitative discussion of their relevance. It focuses on eleven choke points where the optimizations are beneficial independently of the database system. Of these, the flattening of subqueries and the placement of predicates have the biggest impact.

We find significant performance penalties when using Apache Beam for application development in the surveyed systems.

@inproceedings{dreseler2018, abstract = {Research in data management profits when the performance evaluation is based not only on individual components in isolation, but uses an actual DBMS end-to-end. Facilitating the integration and benchmarking of new concepts within a DBMS requires a simple setup process, well-documented code, and the possibility to execute both standard and custom benchmarks without tedious preparation. Fulfilling these requirements also makes it easy to reproduce the results later on. The relational open-source database Hyrise (VLDB, 2010) was presented to make the case for hybrid row- and column-format data storage. Since then, it has evolved from being a single- purpose research DBMS towards becoming a platform for various projects, including research in the areas of indexing, data partitioning, and non-volatile memory. With a growing diversity of topics, we have found that the original code base grew to a point where new experimentation became unnecessarily difficult. Over the last two years, we have re-written Hyrise from scratch and built an extensible multi-purpose research DBMS that can serve as an easy-to-extend platform for a variety of experiments and prototyping in database research. In this paper, we discuss how our learnings from the previous version of Hyrise have influenced our re-write. We describe the new architecture of Hyrise and highlight the main components. Afterwards, we show how our extensible plugin architecture facilitates research on diverse DBMS-related aspects without compromising the architectural tidiness of the code. In a first performance evaluation, we show that the execution time of most TPC-H queries is competitive to that of other research databases.}, author = {Dreseler, Markus and Kossmann, Jan and Boissier, Martin and Klauck, Stefan and Uflacker, Matthias and Plattner, Hasso}, booktitle = {22nd International Conference on Extending Database Technology (EDBT)}, keywords = {adm hyrise mboissierselected myown}, month = 3, pages = {313-324}, title = {Hyrise Re-engineered: An Extensible Database System for Research in Relational In-Memory Data Management}, year = 2019 }

Computer Science teachers often incorporate existing videos, quizzes, and practical programming exercises from Massive Open Online Courses (MOOCs). However, teachers' options to adapt the content to their specific needs are currently limited. Based on a qualitative survey with thirteen teachers, we developed a software prototype which allows teachers to create their own interactive worksheets consisting of texts, videos, quizzes, and practical programming exercises. Additionally, teachers can embed and further customize existing exercises from MOOCs.

Scrum, the most popular agile method, provides dedicated retrospective meetings to reflect on the last development iteration and to decide on process improvement actions. However, agile methods do not prescribe how these improvement actions should be identified, managed or tracked in detail. The approaches to detect and remove problems in software development processes are therefore often based on intuition and prior experiences and perceptions of team members. Previous research in this area has focused on approaches to elicit a team's improvement opportunities as well as measurements regarding the work performed in an iteration, e.g. Scrum burn-down charts. Little research deals with the quality and nature of identified problems or how progress towards removing issues is measured. In this research, we investigate how agile development teams in the professional software industry organize their feedback and process improvement approaches. In particular, we focus on the structure and content of improvement and reflection meetings, i.e. retrospectives, and their outcomes.

Software development methods have introduced frameworks and sets of best practices for certain contexts, providing practitioners with established guidelines for these important choices.

We created a mapping between a selection of these activities and the problems they attempt to solve. We evaluated the created mapping through multiple case studies with software development teams in educational and professional contexts. Our results verify the existence of a relationship between specific retrospective activities and connected retrospective problems. Furthermore, using observational studies we could verify parts of the created problem-activity mapping.}, author = {Matthies, Christoph and Dobrigkeit, Franziska and Ernst, Alexander}, booktitle = {Systems, Software and Services Process Improvement.

@inproceedings{Hiller2018-246, abstract = {Cloud computing offers the potential to store, manage, and process data in highly available, scalable, and elastic environments. Yet, these environments still provide very limited and inflexible means for customers to control their data. For example, customers can neither specify security of inter-cloud communication bearing the risk of information leakage, nor comply with laws requiring data to be kept in the originating jurisdiction, nor control sharing of data with third parties on a fine-granular basis. This lack of control can hinder cloud adoption for data that falls under regulations. In this paper, we show in six use cases how cloud environments can be enriched with policy language support to give customers control over cloud data. Our use cases are based on realizing policy language support in all three cloud environment layers, i.e., IaaS, PaaS, and SaaS. Specifically, we present policy-aware resource management (with OpenStack) and dynamic network configuration. With CERN's big data storage and the in-memory database Hyrise, we show realization for storage and further exemplify policy-aware cloud processing by network function virtualization which enables Orange to offload customer home gateways to the cloud. Finally, we discuss benefits of policy support in F-Secure's Security Cloud. These use cases show the feasibility of realizing customer control with policy support in the cloud. Thus, our work enables customers with regulated data to tap cloud benefits and significantly broadens the market for cloud providers.}, author = {Hiller, Jens and Kimmerlin, Mael and Plauth, Max and Heikkila, Seppo and Klauck, Stefan and Lindfors, Ville and Eberhardt, Felix and Bursztynowski, Dariusz and Santos, Jesus Llorente and Hohlfeld, Oliver and Wehrle, Klaus}, booktitle = {2018 IEEE International Conference on Cloud Engineering (IC2E)}, keywords = {cloud_computing in-memory_database policy_language}, title = {Giving Customers Control over Their Data: Integrating a Policy Language into the Cloud}, year = 2018 }

In this paper, we present our approach of analyzing software repositories in order to gauge student behavior during project work. We evaluate this approach in a case study of a university undergraduate software development course teaching agile development methodologies. Surveys revealed positive attitudes towards the course and the change of employed development methodology from Scrum to Kanban. However, surveys were not usable to ascertain the degree to which students had adapted their workflows and whether they had done so in accordance with course goals. Therefore, we analyzed students' software repository data, which represents information that can be collected by educators to reveal insights into learning successes and detailed student behavior. We analyze the software repositories created during the last five courses, and evaluate differences in workflows between Kanban and Scrum usage.}, author = {Matthies, Christoph and Teusner, Ralf and Hesse, Guenter}, booktitle = {IEEE Frontiers in Education Conference (FIE)}, keywords = {Education Kanban Scrum development_artifacts software_engineering}, month = {oct}, pages = {1-9}, title = {Beyond Surveys: Analyzing Software Development Artifacts to Assess Teaching Efforts}, year = 2018 }

We propose the architecture of a generalized framework that enables seamless integration of self-driving capabilities into database systems. Thereby, general-purpose database systems can transform themselves into systems tailored to a specific use case.

Both effects are challenging as competitive markets are complex and computations of optimized pricing adjustments can be time-consuming. We analyze stochastic dynamic pricing models under oligopoly competition for the sale of perishable goods. To circumvent the curse of dimensionality, we propose a heuristic approach to efficiently compute price adjustments. To demonstrate our strategy’s applicability even if the number of competitors is large and their strategies are unknown, we consider different competitive settings in which competitors frequently and strategically adjust their prices. For all settings, we verify that our heuristic strategy yields promising results. We compare the performance of our heuristic against upper bounds, which are obtained by optimal strategies that take advantage of perfect price an- ticipations. We find that price adjustment frequencies can have a larger impact on expected profits than price anticipations. Finally, our approach has been applied on Amazon for the sale of used books.

This usually means students are introduced to and work with the currently most popular agile methodology: Scrum. However, as the agile methods employed in the industry change and are adapted to different contexts, university courses must follow suit. A prime example of this is the Kanban method, which has recently gathered attention in the industry. In this paper, we describe a capstone course design, which adds the hands-on learning of the lean principles advocated by Kanban into a capstone project run with Scrum. This both ensures that students are aware of recent process frameworks and ideas as well as gain a more thorough overview of how agile methods can be employed in practice. We describe the details of the course and analyze the participating students' perceptions as well as our observations. We analyze the development artifacts, created by students during the course in respect to the two different development methodologies. We further present a summary of the lessons learned as well as recommendations for future similar courses.

@inproceedings{boissier2018workloaddriven, abstract = {Modern server systems with large NUMA architectures necessitate (i) data being distributed over the available computing nodes and (ii) NUMA-aware query processing to enable effective parallel processing in database systems. As these architectures incur significant latency and throughout penalties for accessing non-local data, queries should be executed as close as possible to the data. To further increase both performance and efficiency, data that is not relevant for the query result should be skipped as early as possible. One way to achieve this goal is horizontal partitioning to improve static partition pruning. As part of our ongoing work on workload-driven partitioning, we have implemented a recent approach called aggressive data skipping and extended it to handle both analytical as well as transactional access patterns. In this paper, we evaluate this approach with the workload and data of a production enterprise system of a Global 2000 company. The results show that over 80% of all tuples can be skipped in average while the resulting partitioning schemata are surprisingly stable over time.}, author = {Boissier, Martin and Kurzynski, Daniel}, booktitle = {2018 IEEE 34th International Conference on Data Engineering Workshops}, keywords = {myown}, month = 4, pages = {116-121}, title = {Workload-Driven Horizontal Partitioning and Partition Pruning for Large HTAP Systems}, year = 2018 }

@article{perscheid2018ebola, abstract = {Background: Since the beginning of the Ebola outbreak in West Africa in 2014, more than 11,000 people died. For outbreaks of infectious diseases like this, the rapid implementation of control measures is a crucial factor for containment. In West African countries, outbreak surveillance is a paper-based process with significant delays in forwarding outbreak information, which affects the ability to react adequately to situational changes. Our objective therefore was to develop a tool that improves data collection, situation assessment, and coordination of response measures in outbreak surveillance processes for a better containment. Methods: We have developed the Surveillance and Outbreak Response Management System (SORMAS) based on findings from Nigeria's 2014 Ebola outbreak. We conducted a thorough requirements engineering and defined personas and processes. We also defined a data schema with specific variables to measure in outbreak situations. We designed our system to be a cloud application that consists of interfaces for both mobile devices and desktop computers to support all stakeholders in the process. In the field, health workers collect data on the outbreak situation via mobile applications and directly transmit it to control centers. At the control centers, health workers access SORMAS via desktop computers, receive instant updates on critical situations, react immediately on emergencies, and coordinate the implementation of control measures with SORMAS. Results: We have tested SORMAS in multiple workshops and a field study in July 2015. Results from workshops confirmed derived requirements and implemented features, but also led to further iterations on the systems regarding usability. Results from the field study are currently under assessment. General feedback showed high enthusiasm about the system and stressed its benefits for an effective outbreak containment of infectious diseases. Conclusions: SORMAS is a software tool to support health workers in efficiently handling outbreak situations of infectious diseases, such as Ebola. Our tool enables a bi-directional exchange of situational data between individual stakeholders in outbreak containment. This allows instant and seamless collection of data from the field and its instantaneous analysis in operational centers. By that, SORMAS accelerates the implementation of control measures, which is crucial for a successful outbreak containment.}, author = {Perscheid, Cindy and Benzler, Justus and Hermann, Claus and Janke, Michael and Moyer, David and Laedtke, Todd and Adeoye, Olawunmi and Denecke, Kerstin and Kirchner, Göran and Beerman, Sandra and Schwarz, Norbert and Tom-Aba, Daniel and Krause, Gérard}, journal = {Frontiers in ICT}, keywords = {Ebola_surveillance_process cp epidemiology healthcare infectious_diseases mobile_applications requirements_engineering}, month = {April}, pages = 7, title = {Ebola Outbreak Containment: Real-Time Task and Resource Coordination With SORMAS}, volume = 5, year = 2018 }

@inproceedings{teusner2018stays, abstract = {This work presents insights about the long-term effects and retention rates of knowledge acquired within MOOCs.

In this paper, we analyze course scores, quiz results and self-stated skill levels of our participants. The aim of our analysis is to uncover factors influencing the retention of acquired knowledge, such as time passed or knowledge application, in order to improve long-term success. While we know that some participants learned the programming basics within our course, we lack information on whether this knowledge was applied and fortified after the course's end. To fill this knowledge gap, we conducted a survey in 2018 among all participants of our 2015 and 2017 programming MOOCs. The first part of the survey elicits responses on whether and how MOOC knowledge was applied and gives participants opportunity to voice individual feedback. The second part of the survey contains several questions of increasing difficulty and complexity regarding course content in order to learn about the consolidation of the acquired knowledge. We distinguish three programming knowledge areas in the survey: First, understanding of concepts, such as loops and boolean algebra. Second, syntax knowledge, such as specific keywords. Third, practical skills including debugging and coding. We further analyzed the long-term effects separately per participant skill group. While answer rates were low, the collected data shows a decrease of knowledge over time, relatively unaffected by skill level. Application of the acquired knowledge improves the memory retention rates of MOOC participants across all skill levels.}, author = {Teusner, Ralf and Matthies, Christoph and Staubitz, Thomas}, booktitle = {2018 IEEE Frontiers in Education Conference (FIE)}, keywords = {myown}, title = {What Stays in Mind? - Retention Rates in Programming MOOCs}, year = 2018 }

Since advantages of a reduced footprint are manyfold, the issue is of high importance for main memory-resident databases. In this paper, we present our work on Hyrise and discuss how we break down this challenge into three aspects in order to reduce the main memory consumption without losing the performance advantage of in-memory databases. First, we reduce existing allocations by efficiently selecting indices and workload-driven compression configurations for table data. Second, we use hybrid table layouts to tier data with minimal impacts on the runtime performance. Third, we employ data structures that efficiently eliminate unnecessary accesses to secondary storage.

We analyze the {DTRS}11 corpus, comprising 16 sessions of design conversation that contain 9830 sentences, with automated Latent Semantic Analysis ({LSA}) to identify potential low coherent turns. We argue that an additional manual coherence analysis with the Topic Markup Scheme ({TMS}) further qualifies preselected turns. This mixed method procedure constitutes a promising pragmatic instrument for locating low coherent turns in large corpora. 297 distinct low coherent turns out of a total amount of 6072 turns were successfully retained. The selected data contains twice as much turns that shift the focus of attention within an existing design issue as turns that interrupt and introduce a new design issue.

@inproceedings{teusner2017aspects, abstract = {Massive Open Online Courses (MOOCs) focus on manifold subjects, ranging from social sciences over languages to technical skills, and use different means to train the respective skills. MOOCs that are teaching programming skills aim to incorporate practical exercises into the course corpus to give students the hands-on experience necessary for understanding and mastering programming. These exercises, apart from technical challenges, come with a series of questions to be addressed, for example: which fraction of the participants' time should they take (compared to video lectures and other course activities), which difficulty should be aimed for, how much guidance should be offered and how much repetition should be incorporated? The perceived difficulty of a task depends on previous knowledge, supplied hints, the required time for solving and the number of failed attempts the participant made. Furthermore, the detail and accuracy of the problem description, the restrictiveness of the applied test cases and the preparation provided specifically for a given exercise also influence the perceived difficulty of a task. In this paper, we explore the data of three programming courses to find criteria for optimal practical programming exercises. Based on over 3 million executions and scoring runs of participants' task submissions, we aim to deduct exercise difficulty, student patterns in approaching the tasks and potential flaws in task descriptions and preparatory videos. We compare our findings to in class trainings and traditional, mostly video and quiz based MOOCs.

Continuously analyzing streams of data allows immediate responses to environmental changes. A challenging task in that context is assessing and comparing data stream processing architectures in order to identify the most suitable one for certain settings. The present paper provides an overview about performance benchmarks that can be used for analyzing data stream processing applications. By describing shortcomings of these benchmarks, the need for a new application benchmark in this area, especially for a benchmark covering enterprise architectures, is highlighted. A key role in such an enterprise context is the combination of streaming data and business data, which is barely covered in current data stream processing benchmarks. Furthermore, first ideas towards the development of a solution, i.e., a new application benchmark that is able to fill the existing gap, are depicted.}, author = {Hesse, Guenter and Matthies, Christoph and Reissaus, Benjamin and Uflacker, Matthias}, booktitle = {ACM International Conference on Distributed and Event-based Systems (DEBS)}, keywords = {Benchmark_Development Data_Stream_Processing Internet_of_Things Performance_Benchmarking Stream_Processing esb}, pages = {359-362}, series = {DEBS '17}, title = {A New Application Benchmark for Data Stream Processing Architectures in an Enterprise Context: Doctoral Symposium}, year = 2017 }

Furthermore, teams can detect those parts of the software for which currently no, or only few experts exist and take preventive actions to keep the collective code knowledge and ownership high. We employed the developed approach at a medium-sized company. The results were evaluated with a survey, comparing the perceived and the computed expertise of developers. We show that aggregated code metrics can be used to identify experts for different software components.

The DataRover system presented in this paper simplifies this task by only requiring custom source code for API authentication and querying. Data transformation and linkage is performed based on mappings, which users can define based on sample responses through a graphical front end. This allows storing the same input data in formats and databases most suitable for the intended analysis without requiring additional coding. Furthermore, API responses are continuously monitored to detect changes and allow users to update their mappings and data collectors accordingly.

This approach poses the problem of grading and evaluating practical project work as well as process conformance during development. Yet, few best practices exist for measuring the success of students in implementing agile practices. Most university courses rely on observations during the course or final oral exams. In this paper, we propose a set of metrics which give insights into the adherence to agile practices in teams. The metrics identify instances in development data, e.g. commits or user stories, where agile processes were not followed. The identified violations can serve as starting points for further investigation and team discussions. With contextual knowledge of the violation, the executed process or the metric itself can be refined. The metrics reflect our experiences with running a software engineering course over the last five years. They measure aspects which students frequently have issues with and that diminish process adoption and student engagement. We present the proposed metrics, which were tested in the latest course installment, alongside tutoring, lectures, and oral exams.}, author = {Matthies, Christoph and Kowark, Thomas and Uflacker, Matthias and Plattner, Hasso}, booktitle = {2016 IEEE Frontiers in Education Conference (FIE)}, keywords = {agile imported metrics software_engineering}, month = {October}, pages = {1-5}, publisher = {IEEE}, title = {Agile Metrics for a University Software Engineering Course}, year = 2016 }

We present the first freely available parallel corpus of scientific publications for the biomedical domain. Documents from the ”Biological Sciences” and ”Health Sciences” categories were retrieved from the Scielo database and parallel titles and abstracts are available for the following language pairs: Portuguese/English (about 86,000 documents in total), Spanish/English (about 95,000 documents) and French/English (about 2,000 documents). Additionally, monolingual data was also collected for all four languages. Sentences in the parallel corpus were automatically aligned and a manual analysis of 200 documents by native experts found that a minimum of 79% of sentences were correctly aligned in all language pairs. We demonstrate the utility of the corpus by running baseline machine translation experiments. We show that for all language pairs, a statistical machine translation system trained on the parallel corpora achieves performance that rivals or exceeds the state of the art in the biomedical domain. Furthermore, the corpora are currently being used in the biomedical task in the First Conference on Machine Translation (WMT’16).}, author = {Neves, Mariana and Yepes, Antonio Jimeno and Névéol, Aurélie}, booktitle = {Proceedings of the Tenth International Conference on Language Resources and Evaluation (LREC 2016)}, keywords = {biomedicine machine_translation parallel_corpus}, publisher = {European Language Resources Association (ELRA)}, title = {The Scielo Corpus: a Parallel Corpus of Scientific Publications for Biomedicine}, year = 2016 }

The knowledge about highly frequented regions as well as peak times in specific areas provides a crucial business advantage to competitors. Today, business relevant decisions about the positioning of service providers and advertising spaces or the balancing of capacity are primarily based on experience only. In this paper, we present a novel approach to gain knowledge about the distribution of potential customers over time and space based on the data of taxi rides, which have been recorded for documentation purposes. By leveraging the performance of in-memory databases, we build an applica- tion, which allows the user to analyze about 700 million taxi rides in real-time. The application allows companies to get an impression in which areas and in what timeframes they can reach a large audience of potential customers. Additionally, we demonstrate that the developed visualization concept enables the comparison of different regions and allows to analyze trends in the customer flow over time.}, author = {Richly, Keven and Teusner, Ralf}, booktitle = {The 2nd EAI International Conference on IoT in Urban Space (Urb-IoT)}, keywords = {imported}, title = {Where is the Money Made?

@inproceedings{matthies2016icse, abstract = {Agile methods are best taught in a hands-on fashion in realistic projects. The main challenge in doing so is to assess whether students apply the methods correctly without requiring complete supervision throughout the entire project. This paper presents experiences from a classroom project where 38 students developed a single system using a scaled version of Scrum. Surveys helped us to identify which elements of Scrum correlated most with student satisfaction or posed the biggest challenges. These insights were augmented by a team of tutors, which accompanied main meetings throughout the project to provide feedback to the teams, and captured impressions of method application in practice. Finally, we performed a post-hoc, tool-supported analysis of collaboration artifacts to detect concrete indicators for anti-patterns in Scrum adoption. Through the combination of these techniques we were able to understand how students implemented Scrum in this course and which elements require further lecturing and tutoring in future iterations. Automated analysis of collaboration artifacts proved to be a promising addition to the development process that could potentially reduce manual efforts in future courses and allow for more concrete and targeted feedback, as well as more objective assessment.}, address = {New York, NY, USA}, author = {Matthies, Christoph and Kowark, Thomas and Richly, Keven and Uflacker, Matthias and Plattner, Hasso}, booktitle = {Proceedings of the 38th International Conference on Software Engineering Companion}, keywords = {Scrum classroom_project collaboration_analysis imported software_engineering}, month = 5, pages = {313-322}, publisher = {ACM}, series = {ICSE '16}, title = {How Surveys, Tutors, and Software Help to Assess Scrum Adoption in a Classroom Software Engineering Project}, year = 2016 }

@inproceedings{matthies2016aseeif, abstract = {Teaching students the basics of agile software development, by pairing lectures with a practical project, has been a part of computer science curricula for the last decades. However, the structure of these projects is often not agile and adaptable itself, in the way how teams are formed, workload is assigned, and meetings are organised. This restricts the areas that students can gather firsthand experiences in. In this paper we describe a university software engineering course which applies the values of the Agile Manifesto to the course design itself. Students work in self-organizing teams and are given significant authority and responsibility for their work, including planning, scheduling, and workload assignment. During the project they are guided by tutors and supported by a minimal amount of traditional lectures. We regularly assess learning progress and satisfaction via surveys and compare the results to those of more controlled course setups. We have observed positive student attitudes towards the self-organizing approach, with no adverse effects of the novel course design in terms of participant satisfaction or learning success. This confirms that the benefits of agile values, reported in the literature, are also applicable in the domain of education on the subject and can help increase student engagement and provide a better learning experience.}, author = {Matthies, Christoph and Kowark, Thomas and Uflacker, Matthias}, booktitle = {2016 American Society for Engineering Education (ASEE) International Forum}, keywords = {imported}, month = 6, title = {Teaching Agile the Agile Way — Employing Self-Organizing Teams in a University Software Engineering Course}, year = 2016 }

@conference{Lars2015a, abstract = {Value driver trees are a well-known methodology to model dependencies such as the definition of key performance indicators. While the models have well-known semantics, they lack the right tool support for business simulations, because a flexible implementation that supports multidimensional, hierarchical value driver trees and data bindings is very complex and computationally challenging. This paper tackles this problem by proposing an approach for generic enterprise simulations which are based on value driver trees. Our approach is two-fold: we present the definition of a simulation meta model at design time, and the run-time simulation tool. The simulation meta model describes the structure of the dependency graph, the data binding, and the parametrization of the model to simulate data changes. The simulation tool can then be used to create and edit simulation model instances and run simulations in real-time by leveraging an in-memory column store. Besides the formal description of the approach, this work presents a prototypical implementation of the simulation tool and an evaluation using data of a consumer packaged goods company.}, author = {Butzmann, Lars and Klauck, Stefan and Mueller, Stephan and Uflacker, Matthias and Plattner, Hasso and Sinzig, Werner}, booktitle = {Datenbanksysteme für Business, Technologie und Web (BTW), 16.

@inproceedings{David2015d, abstract = {In-memory database systems are well-suited for enterprise workloads, consisting of transactional and analytical queries. A growing number of users and an increasing demand for enterprise applications can saturate or even overload single- node database systems at peak times. Better performance can be achieved by improving a single machine’s hardware but it is often cheaper and more practicable to follow a scale-out approach and replicate data by using additional machines. In this paper we present Hyrise-R, a lazy master replication system for the in-memory database Hyrise. By setting up a snapshot-based Hyrise cluster, we increase both performance by distributing queries over multiple instances and availability by utilizing the redundancy of the cluster structure. This paper describes the architecture of Hyrise- R and details of the implemented replication mechanisms. We set up Hyrise-R on instances of Amazon’s Elastic Compute Cloud and present a detailed performance evaluation of our system, including a linear query throughput increase for enterprise workloads.}, author = {Schwalb, David and Kossmann, Jan and Faust, Martin and Klauck, Stefan and Uflacker, Matthias and Plattner, Hasso}, booktitle = {Proceedings of the 3rd VLDB Workshop on In-Memory Data Mangement and Analytics (IMDM), in conjunction with VLDB 2015 Kohala Coast, Hawaii}, keywords = {HYRISE imported}, title = {Hyrise-R: Scale-out and Hot-Standby through Lazy Master Replication for Enterprise Applications}, year = 2015 }

This platform permits high performance OLAP with massive scale-out capabilities, while concurrently allowing OLTP workloads. This dual capability enables analytics over real-time changing data and allows fine grained user-specified service level agreements (SLAs) on data freshness. We advocate the decoupling of core database components such as query processing, concurrency control, and persistence, a design choice made possible by advances in high-throughput low-latency networks and storage devices. We provide full ACID guarantees and build on a logical timestamp mechanism to provide MVCC-based snapshot isolation, while not requiring synchronous updates of replicas. Instead, we use asynchronous update propagation guaranteeing consistency with timestamp validation. We provide a view into the design and development of a large scale data management platform for real-time analytics, driven by the needs of modern enterprise customers.}, author = {Goel, Anil and Pound, Jeffrey and Auch, Nathan and Bumbulis, Peter and MacLean, Scott and Färber, Franz and Gropengiesser, Francis and Mathis, Christian and Bodner, Thomas and Lehner, Wolfgang}, journal = {Proceedings of the VLDB Endowment}, keywords = {distributed_database htap}, title = {Towards Scalable Real-time Analytics: An Architecture for Scale-out of OLXP Workloads}, year = 2015 }

@article{alexandrov2011myriad, abstract = {The need for efficient data generation for the purposes of testing and benchmarking newly developed massively-parallel data processing systems has increased with the emergence of Big Data problems. As synthetic data model specifications evolve over time, the data generator programs implementing these models have to be adapted continuously -- a task that often becomes more tedious as the set of model constraints grows. In this paper we present Myriad - a new parallel data generation toolkit. Data generators created with the toolkit can quickly produce very large datasets in a shared-nothing parallel execution environment, while at the same time preserve with cross-partition dependencies, correlations and distributions in the generated data. In addition, we report on our efforts towards a benchmark suite for large-scale parallel analysis systems that uses Myriad for the generation of OLAP-style relational datasets.}, author = {Alexandrov, Alexander and Schiefer, Berni and Poelman, John and Ewen, Stephan and Bodner, Thomas and Markl, Volker}, journal = {Proceedings of the PACT Workshop on Architectures and Systems for Big Data}, keywords = {benchmarking distributed_database}, title = {Myriad: Parallel Data Generation on Shared-nothing Architectures}, year = 2011 }

@conference{Alexander2011a, abstract = {Available-To-Promise (ATP) is an application in the context of Supply Chain Management (SCM) systems and provides a checking mechanism that calculates if the desired products of a customer order can be delivered on the requested date. Modern SCM systems store relevant data records as aggregated numbers which implies the disadvantages of maintaining redundant data as well as inflexibility in querying the data. Our approach omits aggregates by storing all individual data records in an in-memory, column-store and scans through all relevant records on-the-fly for each check. We contribute by describing the novel data organization and a lockingfree, highly-concurrent ATP checking algorithm. Additionally, we explain how new business functionality such as instant rescheduling of orders can be realized with our approach. All concepts are implemented within a prototype and benchmarked by using an anonymized SCM dataset of a Fortune 500 consumer products company. The paper closes with a discussion of the results and gives an outlook how this approach can help companies to find the right balance between low inventory costs and high order fulfillment rates.}, author = {Zeier, Alexander and Plattner, Hasso and Butzmann, Lars and Klauck, Stefan and Tinnefeld, Christian and Mueller, Stephan}, booktitle = {Datenbanksysteme in Business, Technologie und Web (BTW 2011), 14.
