All script applications like forums or web stores keep their information within a database - a group of cells and tables which contains all the website data like items, prices, comments, and so forth. Each time you open a specific page, the script connects to the database and retrieves the required data, then displays it. The intermediary software that connects the script and the database is known as a database management system and amongst the most famous ones is MySQL. The latter is commonly used as it operates on different platforms (Windows, UNIX, Linux) and with a number of scripting languages (PHP, Java, Perl, Python), not mentioning its wonderful effectiveness even with massive databases. Many widely used platforms including Joomla or WordPress employ MySQL databases to save their content.
