2 Part B Retiree Day Member Person Employee Gym Member Janitor Manager VIP Member Physical Therapist Standard Member You need to organize these entities into a hierarchy that makes sense. Then draw a supertype/subtype hierarchy for them. Here are some rules: A person can be an employee, retiree and/or a gym member at once. These roles overlap with each other. So, for example someone can be a retiree, an employee and still have a gym membership. An employee can be a manager, janitor, typical worker employee or a physical therapist. They cannot have two or more job titles. Employees can only have one job title. You can say that none of the janitors are physical therapists or managers at the gym for example. You could also say that a typical worker is not a manager. A gym member can have one of three different types of memberships. They can have a day pass, be a standard member or be a VIP. The VIP members pay more money, but they get access to the physical therapists and yoga instructors. Every entity above is a human person. Employees are not given gym memberships for free as part of their employment. Save
