MySQL is one of the most widespread database admin systems available. A database is a set of cells with info which are arranged in tables and the management system is the piece of software which links the data to a script application. As an illustration, a forum stores all posts, usernames, avatars etc inside a database and each time a website visitor opens a specific thread, the forum script connects to the database and “calls” the content which has to be displayed on a particular page. MySQL is quite popular because of its excellent functionality, convenience and the fact that it can work with many popular scripting languages including PHP, Python, Perl, etcetera. All dynamic Internet sites which are developed with a script-driven app need some kind of database and a lot of the most widely used ones including Joomla™, Moodle, Mambo and WordPress use MySQL.
