MonetDB provides an SQL compliant database interface, supporting the common SQL features such as keys, joins, views, triggers and stored procedures Furthermore, it supports full-ACID properties for concurrent transactions, SQL:1999 ROLLUP, CUBE and GROUPING SETS, SQL:2003 merge statements, and SQL:2011 window functions

Achieving high-performance for heavy analytical workloads requires fine-grained optimisation throughout the database software stack In MonetDB, your queries are translated by tens of relational optimisers to a parallel execution plan leveraging the modern multi-core CPU architecture, on a column-based storage model designed primarily for analytical data processing Where applicable, additional indices are used to accelerate your queries' execution

Next to user-defined aggregate, filter, window and table returning SQL functions, MonetDB also supports UDFs implemented using Python, R or C/C++ with zero data conversion costs

With her roots in core database research, MonetDB closely follows the frontline of the technological development Since her first release in 2004, MonetDB constantly matures proven research ideas into production-level features and contributes product improvements back to the community
