List- My Opinion:
The purpose of Normalization is to reduce redundant storage. It is a trade off between affording redundancy(as far as you can?)and avoiding to many joins later. It can not be true accross the board. Designers should go by the merit/requirements of the application. If database is normalized as and where it is possible(i.e. up to Boyce-Codd Normal Form); it might become a nightmare while trying to run BUSINESS OBJECTS/COGNOS/etc against it. As Hanna just mentioned joining 17 tables. AT my present work place I am dealing with a db which is so poorly designed. Now to be able to support BUSINESS OBJECT the developers are kind of taking band aid approach - asking for denormalizing the db tables with so called "WORK TABLES" - It is serving two purposes, saving them from "coding nightmares" and improving apps performance. As far as RI is concerned I have seen in places they do not use RI rather loves to maintain data integrity by using triggers. My opinion on this - This is more of a preference than to do with any technicality. I am for RI.
