MySQL (pronounced ‘my-ess-cueel’) is an open source, true multiuser, multi-threaded relational database management system (RDBMS), that uses Structured Query Language (SQL). MySQL was developed by two Swedes and a Finn — David Axmark, Allan Larsson and Michael Widenius. It was written in C, C++, and was first released in 1995. Currently, MySQL has over 11 million installations. It’s fast and flexible and allows storage of logs and pictures. Its goals are speed, robustness and ease of use. It’s open source, 100% GPL (General Public License) database.
