MySQL

About

MySQL is a FOSS database engine and server. It fills roughly the same niche as Microsoft SQL Server.

The MySQL package (at least in Linux) has a number of helper utilities available, including MySQL Workbench (a combination of the former MySQL Administrator and MySQL Query Browser applications).
