MySQL is an open source relational database management system (RDBMS). It is the world’s most popular open source RDBMS and is currently ranked as the second most popular RDBMS in the world (behind Oracle Database).

MySQL is available as a free download, however, several paid editions are also available which offer additional functionality.

As the name suggests, MySQL is based on SQL. The “My” part is named after co-founder Michael Widenius’ daughter, My.

Who Uses MySQL?

MySQL is used by some of the largest organisations in the world, including Facebook, Google, Twitter, Adobe, Flickr, Alcatel Lucent, Zappos, YouTube, and many more.

However, it is also used by many smaller scale projects such as personal websites or blogs.

MySQL is the default database for the WordPress platform – which at the time of writing, is said to account for more than 26% of all sites on the web. Other content management systems and forum software that use MySQL include TYPO3, MODx, Joomla, phpBB, MyBB, and Drupal.

Who Owns MySQL?
