SQL

MySQL

Database that has a SQL interface. Claims to be ACID[1]-compliant; tries hard to. Same story as with PHP: Large availability, everybody uses it, hardly the best choice.

Food for thought:

PostgreSQL

Full-featured SQL Server. Is ACID[1]-compliant. Needs more maintenance than MySQL. Doesn't have native replication support.

Food for thought:

Oracle

The commercial behemoth.

LDAP

LDAP systems are like Databases too - often they build on a generic database and provide a more specialised view.
