The short answer is no. The longer answer: Core Data isn't a
relational database solution (even though it appears so on the
surface and can use SQLite as a data store... which is a very
different than using it as a database. You can't directly execute
SQL statements for example.) Even if it were, it won't currently
work with 3rd party databases unless you are willing to take on a
fairly significant development effort to bypass much of what Core
Data does (and losing many of the benefits) and probably experience
performance issues. Part of the significant development effort is
the problem that CD owns it's schema and won't directly map to an
external schema.
It's great for what it does but if you read the docs ignoring every
reference to SQLite, it will be easier to see it for what it is.
Search the list archives for several other discussions on this topic
and I'd suggest you don't bang your head trying to make it work: it
probably won't get you where you're going.

Hi,
I've read info about core data and it seems to be interesting for
our apps.
Here's what I have. There's existing database model -tables- which
is used within PrimeBase SQL database
Plans exist to migrate to Oracle..
Problem of-course is that we can't change database scheme.. :( So
we need to find a way -rather obvoius?- to make classes on top of
existing scheme to use with core data. That is why CD seems to be
nice to me..
Guys, is it possible to use existing tables within SQL database.
What should I do to enable PrimeBase backend for Core Data
Could you please clear things?
Thanks in advance
