Can you figure out by considering an erd for a university that has a superclass of EMPLOYEE with two subclasses, FACULTY and STAFF. The entity class EMPLOYEE has an attribute of type. The attribute type serves as the only constraint that determines whether or not a record is FACULTY or STAFF. Choose the most appropriate description for the relationship between the subclasses and the superclass. Find out which right: a. Subclasses are representative as attribute defined specialization b. Subclasses are representative of a user defined specialization. c. Subclasses are not classified as a specialization

Please figure out by Considering an ERD for a university that keeps track of a superclass of STUDENTS that has two subclasses: GRADUATE and UNDERGRADUATE. The GRADUATE subclass has two of its own subclasses: TEACHING_ASSISTANT and RESEARCH_ASSISTANT. The graduate students at this university are expected to serve as either a TA or an RA, but cannot serve as both at the same time. Select the terms that best describe this specialization. Can you guess which is right? a. Total and disjoint. b. Partial & overlapping c. Total & overlapping. Get the correct response.
