Subtype PK Name
I have a supertype table "Persons" (PK - "PersonID") and several subtype tables. Is it necessary/mandatory to name the PK of all the subtype tables "PersonID"?

One of the subtype tables is "Employees". I want to use "EmployeeID" as the PK (i.e., PersonID in Persons is related 1-1 to EmployeeID in Employees).

Thanks!

no, it is not necessary that they have the same column name
