Ovid on How to fake DB design.

Database based contain information which is stored in tables.  If you tell yourself a story about the database (“we have orders and users and items” or “we have courses and users and (because of our patents) users of various types in courses”) we have a start on the tables we SHOULD use in the database.  This is intended to make at least an attempt to create a normalized database design.
