Scenario: A university has staff members who can be either professors or administrative staff. How would you model this scenario using superclass and subclass relationships?
- Create separate databases for professors and administrative staff
- Create separate tables for professors and administrative staff
- Use a single table for all staff members
- Use a superclass-subclass relationship with a staff superclass and professor/administrative staff subclasses
In this scenario, the best approach is to use a superclass-subclass relationship. By having a staff superclass and professor/administrative staff subclasses, you can inherit common attributes from the superclass while allowing specific attributes for each subclass. This promotes data integrity and reduces redundancy.
