- The August 1, 1992 issue of Datamation has an article listing over 100 dbms,
- what platforms they run on, what type of user interfaces are available, whether
- they support SQL, what add-ons are available, etc.
-
- The article makes no attempt to rate these products. As another poster pointed
- out, it is difficult to rate the products in any truly objective way.
-
- My personal experiences (as if they will have any weight :-o )
- --------------------------------------------------------------
- IDEAL - bought up by the giant CA PacMan, is a superb development environment
- and 4gl for mainframe applications. Dynamite product 4 years ago.
- I don't know what CA has done with the product, but it was excellent.
-
- XDB - Good product for PC systems but notorious problems with memory management
- Terrific front-end for development, increasingly sophisticated programmin
- language. The vendor pulled a NLM version of the product from the market
- due to 'lack of demand'. Reportedly a great product for developing DB2
- applications on the desktop. This product could be great, but the
- development staff need to institute some formal programming disciplines.
-
- Revelation - I worked with Rev/G for about 2 years. It drove me right up a
- wall. I managed to hack it into something reasonable, but I denounce
- what IMHO is an insurmountable design flaw - every field is variable
- length. Rev fans no doubt are about to flame me, but consider: in most
- database applications, 90% of your data is of known *fixed* length or at
- least a reasonable maximum can be determined. The 'all variable' paradigm
- ignores this little fact of life with no profit. I tried ARev v1 and
- found it overwhelmingly cumbersome. Given the wide variety of reasonably
- good products on the market, I can't see investing the time in Revelation
- (zip up my Nomex suit for the flames-to-come).

- So there's a detailed response. These opinions do not neccessarily reflect the
- opinions of my employer or anybody else. Hokay?
