We at IBBC-TNO are investigating what benefits/penalties might be expected from the use of object-oriented DBMS's. I know of the existance of several products in the US (Vbase, Ontos, GemStone, Gbase, IRIS, Postgres, ...). I studied some material of Vbase and Postgres and they look very promising. Does anyone have any pointers-to/comments-on/experience-with (these) object-oriented DBMS products? Currently, to get some experience, we are building a very simple system in 'C'. In order to gather some momentum in this project any comments or suggestions are welcome. -- Werner de Bruijn TEL : (31) 15-606448 IBBC-TNO FAX : (31) 15-620304 P.O.

I'm looking for some basic information on object-oriented databases and how they can be of benefit OVER relational databases. It seems to me that an object-oriented interface to a database is just another layer on top of a database system (say, relational). Also, it would seem that access of data from the database would be at a very fundamental level (the object) and thus would not be able to take advantage of the set processing capabilities of the database system. Can OODBMSs really implement methods against objects at all levels or are objects that are stored in an OODBMS kept at a general level with general methods? I think I'm opening up a can of worms, but what the h***. I have a few ideas on this, but I'm interested getting a better handle on the state of the art first. What do you think? ;-) David Masterson DMasterson@cup.portal.com
