The latter is carried out through special software known as database management system and one of the most widely used ones globally is MySQL. A wide range of script apps are designed to work with MySQL as it is easy to use, it functions perfectly on a server and it's universal as it can perform with famous web programming languages (Java, PHP, Perl, Python) and on numerous server Operating Systems (Linux, UNIX, Windows). There are hundreds of scripts that use MySQL, including really popular ones for instance WordPress, Joomla™ and Moodle.
