The column-store pioneer

The column store technology  of MonetDB has found its way into the product offerings of all major commercial database vendors. Its pioneering role has been internationally recognized with the prestigious ACM SIGMOD Edgar F. Codd Innovation  Award and ACM SIGMOD Systems Award. The market for applications empowered by these techniques provide ample space for further innovation, e.g. as demonstrated by our ongoing projects. At the same time, the landscape for major innovations remain wide open. A peek preview is given in the award winning paper titled: The Researcher's Guide to the Data Deluge: Querying a Scientific Database in Just a Few Seconds.

Column-store features
When your database grows into millions of records spread over lots of tables and used in business or science data warehouse applications, you really want a column-store database management system.

MonetDB innovates at all layers of a DBMS, e.g. a storage model based on vertical fragmentation, a modern CPU-tuned query execution architecture, automatic and self-tuning indexes, run-time query optimization, and a modular software architecture.
