I am looking for information on INGRESS. How many people out there are using it? How do you like it? How does it compare to other Database systems. How much does it usually cost? We are considering it for a large database project. We have looked at RIM and ORACLE, but saw a report that looked pretty good on INGRESS. Please send any information to me, I will summarize to the net. -------------------------------------------------------------------------------- | M.

We've used Ingres (University), Ingres (Commercial), Oracle, Rim, and System 1032 in a variety of environments here at Arizona. The basic answer is that we classify them in three categories: Good Ingres (Commercial), Oracle Mediocre System 1032 Ugly Ingres (University), Rim, Rdb Our criteria, of course, are different from yours. However, Ingres and Oracle are, for all intents and purposes, interchangeable. They are both VERY expensive. Licensing a good sized VAX like an 8650 will run you somewhere in the $50,000 to $100,000 range (depending on what features you want, how you want to pay for it, what maintenance schedule you have, and if you're an educational institution or not). Performance for the two systems, claims of the vendors notwithstanding, is almost identical. You can always make one seem faster than the other, depending on what you're doing. System 1032 is a commercially-oriented system that bows (just barely) to the relational model. It has better performance then Ingres or Oracle, but is a pain to program. The HLI (Host Langauge Interface) is one step above brain-damaged. Our benchmarks were done on a 100-200Mbyte database on a VAXcluster running VMS (fyi). Forget Rim or University Ingres. Either will end up with you disgraced and probably fired. Rdb is Datatrieve with relational terms. Your programmers will love it; your data-retrieval people will hate it. It takes a guru to understand the query language. But it's integrated BEAUTIFULLY with VMS. And has a head-start of 12 months on any other product when new versions of VMS come out. Rdb/SQL may be part of the answer, but we haven't had a chance to work with it yet. If I was asked to recommend a new database system for a new project, I'd have programmers look carefully at Ingres and System 1032 and pick whatever they like better. Note that there are LOTS of other products out there and my opinions are ONLY OPINIONS. +-------------------------------+ | Joel M Snyder | BITNET: jms@arizmis.BITNET | Univ of Arizona Dep't of MIS | Internet: jms@mrsvax.mis.arizona.edu | Tucson, Arizona 85721 | Pseudo-PhoneNET: (602) 621-2748 +-------------------------------+ ICBM: 32 13 N / 110 58 W (I have gotten into trouble too many times to put any faith in disclaimers) "There's nothing here that an overdose of Seconal won't cure."
