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).
- SQL Syntax:
- Versions: stuff particular to specific versions
- /archive: older stuff that probably is no longer applicable
- repair munged tables
- data recovery
