MySQL

MySQL is a relational database management system (RDBMS) that is based on structured query language (SQL).

MySQL is one of the most popular RDBMS with PostreSQL. Its functionalities meet the expectations of all types of application and it is particularly used in the Web domain.

Founded in 1994, the software was first acquired by Sun Microsystems in 2008 and then by Oracle Corporation in 2009, thus delivering the acquisition of two competing products, Oracle Database and MySQL, to the group. The founder of MySQL then left the company to launch MariaDB, a software created from the MySQL source code.

MySQL's open-source configuration allows free use, publication and constant improvement of its source code. In addition, MySQL allows to manage several storage engines within the same database, the most known being MyISAM and InnoDB.
