Well, you can get a lot of mileage out of the theory... I think that
it's not a binary distinction between a model being 'broken' or
'unbroken', it's more of a spectrum between things that are easy and
hard. You can get a lot of mileage out of the RDBMS, and if/when you
get to a point where things start to look difficult ( "Boy, I don't
immediately see a way to do this"), check to make sure that you really
understand the theory, you're "doing it right" -- implementing a good
solution for the problem, and if that fails, maybe you can fudge
something other than the database, because the database is doing so
much else for you.
