Vonder Haar x4126 3E257) Organization: AT&T Bell Laboratories, Columbus Lines: 25 We are developing a system the uses the IDM 500. I think the relational model is a very high level modeling environment for solving (and then re-solving) data modeling problems. As a system developer who likes to prototype, the IDM is fantastic. Of course, there are other database systems that support the relational model, but I only have experience with this one. Our system is: - several 3b20 connected to several IDM 500 via rs232 @ 9600 BAUD The IDM 500 already supports ethernet, but we can't use it yet. - brand new, our users have not really used the system. - We currently support application program with embedded relational (QUEL) commands - We expect the database administrator for our field system to use the interactive realtional query process. Uncertainities about the IDM xxx - It may be difficult to justify spending money for a backend database machine for an application with 10 PCs - Britton-Lee still needs to work on efficiency, they are trying and we haven't really learned about what is available Be sure you check this out.
