>> a primary key should always be a single column <<
Where did you get a stupid idea like that? It was not Dr. Codd, Chris
Date, or anyone else who has written about RDBMS. Can you give ANY
recgonized authority in the field for that statement? Consider
(longitude, latitude) pairs. The only atomic meaning comes from the
pair, not the parts.
Please read any book on RDBMS before you post again.
