I am evaluating Oracle, Ingres and Rdb for a Vax 8250. If any of
you have done a similar exercise or have experience with either of these
products, I'll appreciate hearing from you.
If there are sufficient replys I'll summarize and post it.
Thank you,

I have evaluated RDB at least and would be very interested to hear anything about ORACLE or INGRES. I was using very small records with lots of keys and RDB diesn't like that kind of thing. Apparently, it keeps all duplicate keys in a linear list so deleting a key with a large number of duplicate can take quite a while. I also found some strange bugs such as the fact that you cannot have a field named "description" and other strange things -- particularly with the callable interface. I was trying to simulate a large database and I must add that DEC did tell me that RDB was not good for that. I hope this helps. John

By some chance, I extracted such an evaluation from David Trueman of Microtel Pacific Research posted Nov 27 1985. Mark Savage of Affinitec St Louis mas@afinitc.uucp summarized replies in June 1985 to his questions on relational databases for PCs and UNIX. This also contained a useful criteria list and comments on INGRES, INFORMIX, MISTRESS, etc. Other sources for evaluations are Datapro reports and Hardcopy magazine (DEC users) June 86, occasional DATAMATION and MINI-MICRO-SYSTEMS; I'm sure others on the net can suggest more, and give comments based on experience. I have mailed the the source that I have stored for David's posting to shrimali@cwruecmp.UUCP. But perhaps it is out-of-date by now. We haven't any major use for a database ourselves but from time to time have to point others here in the right direction. At the moment we need a portable VMS/UNIX relational database for a simple application and I wonder if databases like ORACLE and INFORMIX are overkill. How can I explain why DEC RDB (or even DBMS) is not the best answer? *************************************************************************** ____________ Graham Tritt SOWI, Department 34b1 | ________|__ Hasler AG, Belpstr. 23, CH-3000 Berne 14, Switzerland | | _ | | | _| |_ | Telephone: +41 31 632661 | | |_ + _| | X.400: graham@hslrswi.hasler |__| |_| | Bitnet: graham%hslrswi.UUCP@cernvax.BITNET |_________| Uucp: ... {seismo,ukc, ... }!mcvax!cernvax!hslrswi!graham ***************************************************************************
