How to think in schemas?

[Aaron <aaron@justaaron.com>]

What's your favorite reference for "thinking in schemas?"  I don't mean 
just the file format, but also good to best practices for schema design, 
accepted practices, idioms, etc.

For example, in an RDB with "people" data, you might fully normalize the 
schema so that there is one and only one record for a household's 
address, and then associate each person that lives at that address as 
separate records with a foreign key to the address record.  Or, 
depending on needs, you might denormalize that design, so that each 
person's record includes its own copy of the address data.

If you didn't know anything at all about RDBs, you could find many books 
and other references that cover issues like that for RDBs.  Probably 
none to few cover similar issues for ldap schemas.

What do you like?
