Use ER Assistant to draw your diagram. Draw a generalization hierarchy containing Employee, Administrator, and Faculty entities. The Employee entity is the supertype, and the Administrator and Faculty entities are the subtypes. The Employee entity has attributes as follows: EmpNo (primary key), EmpName, and EmpAddress. The Administrator entity has attributes as follows: AdmTitle, AdmContractLength The Faculty entity has attributes as follows: FacTenure, FacRank The generalization hierarchy should be disjoint but not complete.
