Description

Leader of the group Database Architectures: Stefan Manegold.

We, the Database Architectures (DA) research group of CWI, are well known as a top data systems research group, active in the broad area of data (management) systems and infrastructure for supporting data science. Our research group has a strong international reputation in academia and industry for pioneering column store technology, fast compression methods, vectorized query execution, on-line query-driven indexing (cracking), adaptive caching, and integration of statistical languages and analysis in database management systems.


We develop, distribute and maintain the MonetDB open-source system, and we have spawned multiple spin-off companies, including Data Distilleries, VectorWise and MonetDB Solutions. Our team also operates a self-built cluster, SciLens, that – unlike many other computer clusters – is bandwidth-optimized and thus better suited as a data-science infrastructure. We pride ourselves on revealing the real problems in our discipline and coming up with revolutionary solutions that are frequently ahead of their time.

CWI PhD graduate founded record IPO company Snowflake

CWI PhD graduate founded record IPO company Snowflake

Data-warehouse company Snowflake went public this week, reaching an extraordinary market value of $70.4 billion, the largest IPO for a software company ever. Snowflake offers cloud-based data warehousing, whose data storage and query engine contain techniques pioneered in CWI’s Data Architectures group. One of the PhD graduates who developed that technology, former CWI researcher Marcin Żukowski, is co-founder of Snowflake.

Integrating data science and relational systems

Integrating data science and relational systems

Data scientists have largely overlooked relational database systems, even though these could greatly help their research. The systems did not gain traction, because combining them with databases proved to be slow and cumbersome. Now CWI researcher Mark Raasveldt bridges that gap. In his thesis, he proposes several novel techniques that make database management systems easier to use and more efficient.
