: I wouldn't consider it bad practice to do as outlined below. I would,
: however, add an indication in the USER table as to what Type of user
: it is -- an Administrator, a Client, or Staff. Without such a Type
: field,
: you're gonna have to check all 3 tables to see which it's in. The Type
: will point it at a specific table.
What if USER can be both Administrator and Staff (or any other combination)?
