Shouldn't you run your tests *before* rewriting your application? :).
You don't have to answer that.

The logic has been proven. What we want to really test is loading and the remote possibility that the compiler built code based on what we wrote, rather then what we thought. :)

We're also trying to decide whether a single database with multiple
schemas or multiple databases are the best solution.  We've done some
research on this through the archives, and the answer seems to depend on
the database/application design.  Still, we welcome any generic ideas
on this issue as well.

I can help a little bit here.  Yes, this decision will be heavily
influenced by application design.  Let's assume you have to keep
multiple identical table sets (suppose you have multiple companies on
the same server for example).  Here are some general stipulations:

Thanks muchly for your insights. Just the kind of info we're looking for. Now if I could only find that mind reading compiler.

We lean towards multiple databases when thinking about the possible need to bring down a single database without affecting the others. We do require access to multiple datastores, but that is relatively easily done with either schemas or databases with perl and C, which are our tools of choice. These databases are pretty much identical in design, simply for different 'parts' of the business.

Any further thoughts are, of course, still welcome.

Until later, Geoffrey
