I found a link:
http://www.geocities.com/tablizer/oopbad.htm
(and there are others) who suggest that object-oriented databases
aren't a good idea. Tabular databases (and in fact a tabular design
rather than an object-oriented design in general) are more often than
not likely to be a better bet.

But I am of course generalising.
