MonetDB

MonetDB is a high-performance relational database system tailored for analytical processing. It has been designed to deliver fast query results by utilizing fine-grained optimizations and a model specifically suited for analytics. With compliance to advanced SQL standards, it supports concurrent transactions and offers a variety of database management tools. MonetDB allows for the integration of user-defined functions (UDFs) and provides JDBC and ODBC drivers for support across various programming languages.

As an open-source project since 2004, MonetDB has evolved from academic research into a production-level database system that supports a range of applications, including business intelligence, financial analysis, medical data processing, and machine learning. The database is licensed under the Mozilla Public License, version 2.0, which encourages community contributions and development.

The documentation for MonetDB is categorized into three main sections: the User Guide, aimed at general users developing SQL applications; the Administrator Guide for server administrators managing installations and security; and the Developer Guide for those working on the MonetDB code base. These resources provide comprehensive support to users at all levels.
