THis isn’t news but I just recently gave EnterpriseDB a spin.
If imitation is the sincerest form of flattery, Larry Ellison’s giant ego will be getting even bigger.
EnterpriseDB bills itself as an Oracle compatible database. It is PostgeSQL with a PL/SQL and SQLPLUS layer on top of it. Most Oracle PL/SQL apps and scripts are said run on it.
The focus is on the app side. The administration is still largely PostgreSQL though some of the Oracle DBA views are replicated.
With Oracle giving away low end versions, Express and StandardOne, I don’t see a lot of incentive for the Oracle compatibility. PostgreSQL on its own has enough merit that this is still worthwhile though. Some Oracle compatibility is just a bit of icing perhaps.
