When you use a script-driven app for your Internet site, any data that both you and the site users produce will be stored within a database - a collection of info, that is structured in cells and tables for simpler reading and writing. The latter is accomplished by employing special software known as database management system and one of the most popular ones globally is MySQL. A lot of script apps are built to work with MySQL since it’s simple to use, it performs perfectly on a server and it's universal as it can work with common web programming languages (Python, PHP, Perl, Java) and on a number of web server OS (Linux, UNIX, Windows). There are loads of scripts which use MySQL, including quite popular ones like WordPress, Moodle and Joomla.
