MySQL is a relational database management system that is widely used to provide database services for websites, among other purposes. It uses a client-server model that supports both access via general-purpose management tools and connections established using a range of programming languages.
MySQL is a component of the popular LAMP stack for Web servers, with LAMP being an acronym for the Linux kernel, the Apache web server, the MySQL relational database management system and any of PHP, Python, or Perl as web-application programming languages. Versions of MySQL are available under either the GNU General Public License or proprietary licenses. Sun Microsystems purchased MySQL in 2008, and Oracle Corporation purchased Sun Microsystems in 2009.
