MySQL is an open source Relational Database Management System, that is available on many platforms including Microsoft Windows and Linux, and was first released by its Swedish creators back in 1995. The database was bought by Sun Microsystems in 2008, who were subsequently purchased in 2009 by Oracle Corporation.
The database utilises SQL, or Structured Query Language, for accessing data held within it, as well as inserting, updating and deleting the data. Although the most popular use for MySQL is in web applications, in conjunction with a scripting language such as PHP, it can also be used in data warehousing, e-commerce, logging applications and more.
MySQL does not come with a Graphical User Interface (GUI), however, there are a number of applications available, which can be used for this purpose, including, MySQL Workbench, Adminer, phpMyAdmin and SQLyog.
