A colleage of mine who has done a lot of consulting for many years 
explained this technique to me, and I was intrigued with it when I heard 
it, and it's nice for you to share your experience with it.  It does 
indeed seem ahead of its time.  SQL views are another nice derivative of 
the idea.

It seems to me that this idea would work well in a setting where you're 
doing a lot of customization over a vendor's database.  The vendor may 
add new fields, which may force them to recompile a lot of their 
programs, but it wouldn't have much if any impact to your programs.
