Database Architectures

A leading data systems research group, active in the broad area of data (management) systems and infrastructure for supporting data science.

The leader of the group Database Architectures: Stefan Manegold

The Database Architectures (DA) research group of CWI is a top database systems research group in the broad area of data management systems and infrastructure for supporting data science. It is well known in academia and industry for pioneering column store technology, fast compression methods, vectorized query execution, on-line query-driven indexing (cracking), and adaptive caching. It develops, distributes and maintains the MonetDB open-source system, and has spawned multiple spin-off companies (Data Distilleries, VectorWise, MonetDB Solutions). It operates a self-built cluster (SciLens) that unlike many other compute clusters is bandwidth-optimized and thus better suited as a data science infrastructure.
