Am I speaking to the wind .... For Compares, why would you compare the MODEL with the DATABASE...like going from US to London via Tokyo... ... and you get to pay more, like... you pay not for distance, but for "time in the air"... If a tool takes longer to do something, makes more mistakes, is bumpy and complex... you get to pay more.
For compares, someone tell me what beats ActiveCompare: http://www.iraje.com/compare-diff.htm http://www.iraje.com/ActiveCompare_viewlet.html ...and I will switch my tool.

Has some better modeling capability as you might guess, but has some VERY annoying quirks too. You also need to drill down endlessly when doing a compare and I have seen it see two exact tables (even case being the same) and see them as different. The DO have a MATCH button that I would SUPPOSE allows you to re-align them, but I would not know for sure as I get Dr. Watson's whenever I press it and the whole thing crashes! I had a nice BUG last week only. Generated scripts for the model, ran them on the db, then ran a compare from the model to the db. Darn thing came up with differences.... Furthermore, I find that if you work from the Logical Model (like I do), the changes are not equally presented to the physical model.... (ie name change./datatype change) and its NOT consistent with this behavior either! It has a report builder, but it doesn't report on datatypes entered on the Logical side (even though the datatype on the physical MAY be different) = therefore you can't run any consistency reports between the Logical and Physical models. I have been using ERWin both as a modeling tool and a change repository for the model. I like to run several reports against a model (I call them the Sanity Checks Reports).... you know, make sure that all columns named the same (ie DESCRIPTION) are of the same datatype, length, etc..... Anyhow, I can rant and rant. ERWin's BIGGEST Annoyance is my book is that there is no UNDO feature and it is rather easy to accidentally drop and drag either a relationship or field when re-aligning the model...... ugh.... I wish we could get together a group and benchmark some relatively unknown but stable modeling tool who's maker will listen to the DBA community and put their name in the market (IE. give them market share) in exchange for giving our community a tool that would actually work for us and work well!
