My SQL was created by a Swedish company, MySQL AB, founded by David Axmark, Allan Larsson and Michael Widenius. The first version was launched on 23 May 1995.
My SQL is an open-source relational database management system (RDBMS) that uses Structured Query Language (SQL).
SQL is the most popular language for adding, accessing and managing content in a database and it is most known for its quick processing, proven reliability, ease and flexibility of use, being an essential part of almost every open source PHP application.
The software provides tools including CMS systems, forums, galleries, blogs, shopping carts and more. It is available on all major operating systems, including Windows, Linux and Solaris and it is free to use for individuals and non-production environments.
MySQL is also used by many popular websites, including Facebook, Flickr, MediaWiki, Twitter and YouTube.
