Yes.

The Object Database Vendors tried about 3 years ago to come up with a
standard, which I think was called ODMG, however they couldn't agree, and in
some cases, significant differences existed between architectures that
wouldn't allow for such a open standard. In in the case of Objectivity
you're responsible for the physical storage of the objects in clusters of
data, and it pulls down all of the database to the client over time. (If you
want to know more, just ask.) This storage scheme apparently works excellent
for super-colliders but not so great for small-medium applications...

Subject: Proposal? Object Databases


This is more of a question than anything:

I recently attended a presentation on Object Databases.  I've explored
them in the past, but never seen such a clear demonstration of their
strengths.

In the spirit of "I've got a new hammer, what can I hit with it?", my
questions are: given OODB's purported strengths will large sets of
data, would JAMES benefit from supporting an OODB as the repository?
Would this be an appropriate use of OODB?

I've only looked at Ozone-db.org, but the interface to it looked
significantly different than the presented Objectivity.  Is there a lot
of variance in OODB interfaces, such that implementing a general
OODBRepository would be prohibitive?

Thanks for you consideration.

Lance
