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.
- OpenLDAP/slapd: the open source LDAP daemon
- Novell eDirectory/NLDAP: a commercial system
Footnotes
- ↑ 1.1 1.2 Atomicity, Consistency, Isolation, Durability. See The ACID model
