Question

Consider the following EER diagram: The EER diagram provides a conceptual model based on the data requirements for a vehicle management application. It shows a specialization that contains a super class and two subclasses. Based on the EER diagram, a relation model should be constructed as the logical design. Generally, there are two ways to design relational tables based on a specialization. One is a single-table approach, while the other uses multiple tables. You are required to complete the following items. Discuss the pros and cons of the two different approaches (single vs. multiple tables) to mapping a specialization into relational tables. Decide which approach you choose for the specialization in the EER diagram and justify your choice. According to your choice, provide the relational schema which is mapped from the EER diagram. Note that you do not need to provide the domains for the attributes.
