MySQL is among the most commonly used database admin systems on the market. A database is a group of cells with info which are organized in tables and the administration system is the piece of software which links the info to a script app. For instance, a forum stores all usernames, avatars, posts etc in a database and every time a visitor opens a specific thread, the forum script connects to the database and “calls” the content that needs to be displayed on a specific page. MySQL is extremely popular because of its great efficiency, simplicity and the fact that it can operate with numerous popular scripting languages like PHP, Python, Perl, etcetera. All dynamic websites that are built with a script-driven app need some form of database and some of the most popular ones like Joomla, Moodle, Mambo and WordPress employ MySQL.
