[comp.object] Information about Ingres OODB?

Has anyone any information about the so-called Object Orientation of
the next release of Ingres (6.3) due in November?

We have a beta release of Ingres Windows 4GL on a Sun workstation here.  The
GUI is 'Object Oriented'.  As far as I can tell Ingres hasn't become an
Object Oriented database.

Ingres provides an Oject Management Extension (not included with the base
RDBMS price) that allows users to define datatypes and functions that act
on those datatypes.  The new code must then be linked into the DBMS. 
Inheritance, polymorphism, clustered object storage, and atomic treatment of
complex objects are not provided.  Neither is a seamless interface to an OOPL.

This does NOT give you an OODBMS, as a product review of Versant, GemStone, or
ObjectStore will reveal.  It can be a powerfull extension to the relational
model, however.  Ingres should have avoided the misused "O" word.  What they
really give you is more like an ADT facility.
