Object-Oriented databases are similar in concept to the Object-Oriented
application that Revolution is reputed to be. The primary difference is
that they focus more on the data aspects. One of the interesting
features is the idea that children data objects inherit their primary
characteristics from their parent.
Valentina puts itself forward as a OODB with relational aspects as
well. A hybrid, if you will. And if it is as it claims it looks very
promising for something I am intent upon accomplishing come next year.
As it might overcome one of the problems with OODBs mentioned in a
discussion earlier, on this listserv....changes to the data structure
that might require extensive manual intervention in order to maintain
the final application.

Never heard of HyBase before. I'll look into that possibility. I'm
looking at using January for analysis of options and making the
purchases in February, if not sooner.

It was helpful for me.
