I'm looking for statistics that analyze how much more time it takes to re-design a poorly constructed database (including data conversion) vs starting all over from scratch. (primarily MS Access, but I don't think the file type necessarily matters)

Have any of you ever seen any such comparison? We have a division that wants to do their own thing, but then they want IS to fix it after they've made a total mess of things. We'd rather they let us design it from the get-go.

Thanks for yourhelp,
Lynnette

I my experience if the data base is badly designed you cannot fix it with out pretty much rewritting the system. Too much of the logic depends on the structure of the database.

The design is the system. Even if you think you can work it out there will be gotchas to bite you. Reports, instead of being easy, will be impossible.
