Our group includes PostDocs, PhD students, and student assistants, and is headed by Prof. Felix Naumann. If you are interested in joining our team, please contact Felix Naumann.

For bachelor students we offer German lectures on database systems in addition to paper- or project-oriented seminars. Within a one-year bachelor project, students finalize their studies in cooperation with external partners. For master students we offer courses on information integration, data profiling, and information retrieval enhanced by specialized seminars, master projects and we advise master theses.

Most of our research is conducted in the context of larger research projects, in collaboration across students, across groups, and across universities. We strive to make available most of our datasets and source code.

Please do not hesitate to reach out directly to us, if you cannot find a paper, slides, or other research artifacts.

Open Source Release of Stratosphere

We are pleased to announce the release 0.1 of the Stratosphere parallel data analysis framework.

At the current state, the system consists of:

the PACT Programming Model
the Nephele Execution Engine

The system is highlighted by the following features:

Easy definition and massively parallel execution of complex data analysis tasks.
PACT is a generalization and extension of the well-known MapReduce programming model.
A cost-based optimizer compiles PACT programs to Nephele dataflow graphs.
Nephele executes dataflow graphs in a massively parallel and very flexible fashion.

The current release, extensive documentation, and related publications are available on our website

stratosphere.eu

The Stratosphere framework is an outcome of the DFG-funded Stratosphere Collaborative Research Unit in which the Technische Universität Berlin, Humboldt Universität zu Berlin, and the Hasso-Plattner-Institut in Potsdam are jointly researching "Information Management on the Cloud".
