Research Topics

Traditional databases are separated into ones for current data from the day-to-day business processes and ones for reporting and analytics. For fast moving businesses moving data from one silo to another is cumbersome and takes too much time. As a result the new data arriving in the reporting system is already old by the time it is loaded. HYRISE proposes a new way to solve this problem: It analyzes the query input and reorganizes the stored data in different dimensions. In detail, HYRISE partitions the layout of the underlaying tables in a vertical and horizontal manner depending on the input to this layout management component. The workload is specified as a set of queries and weights and is processed by calculating the layout dependent costs for those queries. Based on our cost-model we can now calculate the best set of partitions for this input workload. This optimization allows great speed improvements compared to traditional storage models.

  • Hybrid Data Structures for Main Memory Databases
  • Query Execution in Main Memory Databases
  • Application-specific Data Management in Enterprise Applications
  • Common Data Model (CDM) for combined OLTP and OLAP

I finished is doctoral research at the HPI in October 2012 and graduated summa cum laude from HPI. Beginning in November 2012 I will start a research project at the University of Fribourg together with Prof. Philippe Cudre-Mauorux in the area of graph oriented data structures for In-Memory Database Management Systems
