- HSQLDB 1.8/2.x (internal, used by default) The internal database suits evaluation purposes only; we strongly recommend using an external database in a production environment.
- MySQL 5.0.33+, 5.1.49+, 5.5+ (Please note that due to bugs in MySQL, versions 5.0.20, 5.0.22 and 5.1 up to 5.1.48 are not compatible with TeamCity)
- Microsoft SQL Server 2005, 2008 and 2012 (including Express editions); SSL connections support might require these updates.
- PostgreSQL 8+
- Oracle 10g+ (TeamCity is tested with driver version 10.2.0.1.0)
