Question 2 (Student Inheritance Hierarchy) Draw a UML class diagram for an inheritance hierarchy for students at a university similar to the hierarchy shown in Fig. 11.2. Use Student as the base class of the hierarchy, then extend Student with classes UndergraduateStudent and GraduateStudent. Continue to extend the hierarchy as deeply (i.e., as many levels) as possible. For example, Freshman, Sophomore, Junior and Senior might extend UndergraduateStudent, and DoctoralStudent and MastersStudent might be derived classes of GraduateStudent. After drawing the hierarchy, discuss the relationships that exist between the classes.

Explain how in a protected inheritance, the members of the base class are inherited by a derived class.

Create a UML Class Model based on the requirements . Your Class Model is to include: All classes Attributes and Attribute Types Associations Multiplicity Primary and Foreign keys Any Inheritance, Composition or Aggregation. Building Maintenance system. A rental property management company wants to develop a ‘Building Maintenance System.’ This system will be used by the company to manage maintenance requests from tenants in the several rental buildings that it manages in the city. Each building has a maintenance manager. The maintenance manager is responsible for creating accounts in the system for each tenant in their building. A tenant can rent multiple apartments within the same building. Tenants can submit maintenance requests using this system. Each maintenance request will have a request ID, category, and description. The maintenance manager manages a maintenance crew in their building. Maintenance crew members can be members of more than one maintenance team. Maintenance crew…
