I did some further searching for answers on this and found a bit of chatter, such as
http://c2.com/cgi/wiki?ExtremeProgrammingChallengeThirteen

I have plenty of agile programming and XP books here, but was looking for someone with experience and a data, rather than strictly XP, angle.

For my second question about whether there are other approaches that are as clean in how to determine what is in or out of the data model, I have been unable to find (or dream up) anything else that comes close. The efforts to design for the future with DB's, as with all programming, are so murky as to boil down to "let experience be your guide". So, I'd suggest that a combination of that (experience) and XP just might be the best approach to determine what relations and attributes to include with any particular external version of software.
