MySQL Database – Open Source Database solution

The MySQL Database powers the most demanding Web, E-commerce and Online Transaction Processing (OLTP) applications.

It is a fully integrated transaction-safe, ACID compliant database with full commit, rollback, crash recovery and row level locking capabilities.

MySQL delivers the ease of use, scalability, and performance that has made MySQL the world’s most popular open source database.

Some of the world’s most trafficked websites like Facebook, Google, ticketmaster, and eBay rely on MySQL for their business critical applications.

MySQL ( /mai eskju:’el/ “My S-Q-L”,officially, but also called /mai ‘si:kwel/ “My Sequel”) is the world’s most used open source relational database management system (RDBMS) as of 2008 that runs as a server providing multi-user access to a number of databases.

It is named after co-founder Michael Widenius‘ daughter, My. The SQL phrase stands for Structured Query Language.
The MySQL development project has made its source code available under the terms of the GNU General Public License, as well as under a variety of proprietary agreements.
MySQL was owned and sponsored by a single for-profit firm, the Swedish company MySQL AB, now owned by Oracle Corporation.

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 (and other ‘AMP’ stacks)

LAMP is an acronym for “Linux, Apache, MySQL, Perl/PHP/Python.”

For commercial use, several paid editions are available, and offer additional functionality.

TYPO3, Joomla, WordPress, phpBB, MyBB, Drupal and other software built on the LAMP software stack.

MySQL has Edition as follows.
