There I'd agree with you ... there is the question of *how rigorous* you
want your normalization to be. I tend to hover around the simplest
normal form, most of the time. And I do a few things (such as
polymorhic sub-tables) that would give Fabian Pascal fits :-)
However, there is (in my mind) no question as to whether a database
should be normalized, just how much effort is spent on normalization as
opposed to other considerations (UI, performance, development time).

What do you use? I've given up on OODB interfaces, myself, as I did not
find them helpful, but that's modtly because I was working in MS-land.

Yup. http://www.databasedebunking.com/ Dig through the archives.
