MySQL is a popular choice of database for use in web applications, and is a central component of the widely used LAMP open source web application software stack—LAMP is an acronym for "Linux, Apache, MySQL, Perl/PHP/Python". Free-software-open source projects that require a full-featured database management system often use MySQL.
For commercial use, several paid editions are available, and offer additional functionality. Applications which use MySQL databases include: TYPO3, Joomla, WordPress, phpBB, MyBB, Drupal and other software built on the LAMP software stack. MySQL is also used in many high-profile, large-scale World Wide Web products, including Wikipedia[10], Google[11][12] (though not for searches), Facebook,[13][14][15], Twitter[16], Flickr[17], Nokia.com[18] and YouTube[19]
