The normal forms
First normal form decrees that my data must be rectangular.
Second normal form says that non-key fields need to refer to the entire composite key. If it pertains to only subset of a key a new table should be made to reduce redundancy.

Fourth and Fifth normal forms are really picky, and you have to make really small decomposed tables to satisfy them. I’d rather have a few large ones.
