MySQL is a multithreaded, multi-user, SQL (Structured Query Language) relational database server. MySQL, as free software, utilises the GNU General Public License. The PHP-MySQL combination is also cross-platform.
The Swedish company MySQL AB writes and maintains the system, selling support and service contracts, as well as commercially-licensed copies of MySQL, and employing people all over the world who communicate over the internet. Two Swedes and a Finn founded MySQL AB: David Axmark, Allan Larsson and Michael "Monty" Widenius.
Programming languages�which can access MySQL databases�include C, C++, Eiffel, Smalltalk, Java, Perl, PHP, Python, Ruby, and Tcl; each of these using a specific API. An ODBC interface called MyODBC also exists which allows additional programming languages that support the ODBC interface to communicate with a MySQL. MySQL uses ANSI C as its "native" language.
