%description
    MySQL is a multi-user Relational Database Management System (RDBMS),
    which is controlled through Structured Query Language (SQL)
    operating in full multi-threading mode. The main goals of MySQL are
    speed, robustness and ease of use. MySQL was originally developed
    because of the need for a SQL server that could handle very big
    databases with magnitude higher speed than what any database vendor
    could offer.
