What is MySQL ?
MySQL is a cross platform open source database server software. It is used extensively in web development. MySQL is a multithreaded, multi-user, SQL relational database server (RDBMS) with an estimated six Query installations. MySQL AB makes MySQL available as free software under the General Public License, but they also dual-license it under traditional commercial licensing arrangements for cases where the intended use is incompatible with use of the General Public License.
Unlike projects such as Apache, MySQL is owned and sponsored by a single for-profit firm, the Swedish company MySQL AB, which holds the copyright to most of the codebase.
The company develops 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 work together via the Internet.
MySQL is a small, compact database server ideal for small -and not so small – applications. In addition to supporting standard SQL (ANSI), it compiles on a number of platforms and has multithreading abilities on Unix servers, which make for great performance. For non-Unix people, MySQL can be run as a service on Windows NT and as a normal process in Windows 95/98 machines.
