I'm making a visitor management application and I made three tables namely tblStudent, tblEmployee and tblVolunteer in SQL. I made a table according to the categories of a visitor. Do I still need to make a tblVisitor that would be the "general" table for the three tables made? I'm really confused whether it's needed or not to make a table to join similar attributes of student, employee and volunteer.
