Have you seen a growth in the use of these types of databases? The
only place Ive heard of them used are in university and research
projects. I know there is an atom smasher at Stanford that is using an
OO database called 'Objectivty'.

What is your experience? I dont see them anywhere in the private
sector. I know some vendors have Object Oriented extensions, but very
few people use them.

I love them, and I use them extensively. If you use Java, check out
XL2 and OzoneDB. They are both stable, supported and open source.

There was growth in the early 1990s. I've found it very hard to get any
recent numbers as most of the analysts (Gartner, IDC, ...) appear to have
stopped tracking this technology.

There are some commercial users too.

Yes.

Well, I toured the world (several times) and presented widely on OODBs at
numerous conferences and user group meetings (just did an invited talk on
this topic in Denmark a few weeks ago). People politely listen, but most
are not interested in using OODBs. I also helped put together a couple of
books with case studies:

M.E.S. Loomis and A.B. Chaudhri (eds.) (1998) Object databases in practice
(Upper Saddle River, New Jersey: Prentice-Hall)

A.B. Chaudhri and R. Zicari (eds.) (2000) Succeeding with object
databases: a practical look at today's implementations with Java. and XML
(New York: John Wiley)

There are pockets of use here and there. My experience from the financial
sector is that there was selective use in some companies in the last
decade (e.g. Nomura, JP Morgan, Chase, etc.).

This is probably true. My colleague Paul Brown posts in this group from
time-to-time. He has had extensive experience working with customers using
so-called Object-Relational Databases. He may pick-up and give you more
about where he thinks this technology is used and why.

Zope uses an OODB for everything ...
I have a huge e-commerce site on Zope, and my experience is very
positive.

Jasmine is a nice system, even made an appearance on ER once, box was
sitting on the front desk!?!?!

Used in quite a few commercial multimedia places.

Yes, CA did push Jasmine quite aggressively into MM (I used to work for CA
about 4 years ago). However, once Jasmine had become an "Intelligent
Infrastructure", the OODB side of things really got submerged.
