MySQL is an RDBMS (Relational Database Management System) that is popular with open-source CMSs (Content Management Systems) and large websites and applications like Facebook, YouTube, Flickr, and Twitter. MySQL is one of the key parts of the open-source LAMP (Linux, Apache, MySQL, PHP/Perl/Python) software stack, which WordPress, Drupal, Joomla!, and other popular CMSs use. MySQL is available as an open-source framework called "MySQL Community Server" and as part of a commercial, enterprise solution, such as Oracle’s MySQL Enterprise Server. In addition to open-source functionalities, the enterprise versions of MySQL provide paid users with commercial plugins, technical support, and related solutions to tackle issues such as performance, security, and regulatory compliance.
