Great reporting tools if you can figure out how to use them. (PC) Modelpro (IDEF style) - It's called ERWin under Windows and may be the same product previously mentioned. I seem to remember a different company name though. Decent implementation of IDEF1X. (Mac) Design IDEF. Does IDEF0 and IDEF1X. I found it to be very good. Forces you to follow your data down to the nether levels. Data cannot just 'appear' - has to come from someplace. Changes to one module are reflected throughout. (Mac) Silverrun (Gane/Sarson) - Zerotime - now owned by Peat Marwick very nice product - lots of good checks - documents data streams very nicely. Changes to one module are reflected... Sorry I can't remember company names on all of these. It's also been a couple of years since I did any data modelling - so I can't be very precise on capabilities - they're all sort of a blur. j. _____________________________________________________________________________ Jack Parker | Hewlett Packard, BSMC Boise, Idaho, USA| If you put all of the lawyers in jparker@hpbs3645.boi.hp.com | this country end to end, (208) 396-5388 (W) (208) 384-1623 (H) | it would be a good thing. _____________________________________________________________________________ Any opinions expressed herein are my own and not those of my employers. _____________________________________________________________________________
