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. hal.
