I've been asked to locate any CAD/CAM systems that store their data using commercially available database products. (The CAD/CAM systems I know of all use proprietary databases to store their designs.) I'd appreciate any leads the people in netland could provide me. Please send e-mail; if there's enough interest, I'll summarize the results. Thanks in advance! ------------------------------------------------------------------------------- Rick Simkin || Phone: +1 (508) 685-7200 x128 Samsung Software America, Inc. || Internet: simkin@samsung.com 1 Corporate Drive || UUCP: uunet!ginosko!simkin Andover, Massachusetts 01810 USA || (uunet, cg-atla, ulowell or infinet)

Cbase 1.0 from Univ of Southern California uses Vbase, a commercially available object oriented database from Ontologic. For reference, see the article about it in Proc. IEEE International Conf. on CAD 1988, page 392--395. --- Khe-Sing The @ CS Dept, U Texas Austin.

You will find that it's very difficulty for any existing commercially available DBMS to support the CAD/CAM applications. To be more specific, any of DBMS products based on the relational model has been proven to be insufficient for CAD/CAM area in terms of data modeling capability. Since they don't many critical requirements such as the composite/complex design objects. Your best chance is to look for the DBMS products based on the object model. They don't necessarily solve all of your problems. But they are more close to what you are asking for. Donovan Hsieh Software Methods Lab Hewlett-Packard

My thanks to those people who responded to my request for information about
CAD/CAM products running on top of commercial databases. I've gotten enough
direct inquiries on what information I received that I've decided to post a
summary to the network.
More than one person told me that CAD/CAM developers consider commercially
available DBMSs to be inadequate for the needs of CAD/CAM applications.
However, people also told me the following:
- Cbase 1.0 from the University of Southern California uses VBase as its
database; there's an article about it in Proceedings of the IEEE
International Conference on CAD 1988, pp. 392-395. VBase is produced
by Ontologic.

CAD/CAM data storage.

- Intergraph has just announced its Relational Interface System, which lets
its VAX-based graphics packages run on top of Ingres, Oracle and Informix.
