MonetDB is an open source column-oriented database management system developed at the Centrum Wiskunde & Informatica (CWI) in the Netherlands. It was designed to provide high performance on complex queries against large databases, such as combining tables with hundreds of columns and multi-million rows. MonetDB has been applied in high-performance applications for data mining, online analytical processing, geographic information systems, XML Query (XQuery), text and multimedia retrieval.
MonetDB (initially only called Monet) was first created by 2002 doctoral student Peter Alexander Boncz and professor Martin L. Kersten as part of the 1990s MAGNUM research project at University of Amsterdam. The first version under an open-source software license (a modified version of the Mozilla Public License) was released on September 30, 2004.
MonetDB internal data representation relies on the memory addressing ranges of contemporary CPUs using demand paging of memory mapped files, and thus departing from traditional DBMS designs involving complex management of large data stores in limited memory.
MonetDB introduced innovations at all database management system layers: a storage model based on vertical fragmentation, a modern CPU-tuned query execution architecture that often gave MonetDB a speed advantage on the same algorithm over a typical interpreter-based RDBMS. MonetDB is one of the first database systems to focus its query optimization effort on exploiting CPU caches. MonetDB also features automatic and self-tuning indexes, run-time query optimization, and a modular software architecture.
The MonetDB family consists of:
- MonetDB/SQL: the relational database system
- MonetDB/GIS: extension to MonetDB/SQL with support for the Simple Features standard of OpenGIS
- MonetDB Server: the multi-model database server
