An OODBMS is quite different from a conventional DBMS in a number of
ways, the principal one being that it supports an OO data model (objects,
methods, classes, subclasses) rather than a network/hierarchical/relational/
deductive/semantic/logical/ER data model.  It is also quite different from an 
OOPL in that it usually supports transaction management, multi-user 
concurrency, persistence, queries and various other things.  There are a lot 
of papers out discussing OODBMS issues.  Take a look at the OOPSLA and SIGMOD 
conference proceedings from the last few years, or take a look at the book 

	_Object-Oriented Concepts, Databases, and Applications_, 
	ed. Won Kim and Frederick Lochovsky, ACM Press, 1989.  
	ISBN 0-201-14410-7, $42.75 US.

A new book by Stanley Zdonik on OODBMSs has also just been published, although 
I don't have any info on it.
