The following Figure 2 shows an EER schema for a database that can be used to track sales at a car dealership. Map this schema into a relational data model, including all primary keys and referential integrity constraints (foreign keys). For the VEHICLE to CAR/TRUCK/SUV generalization, consider the four Step 8 options presented in the lecture notes for mapping specializations/generalizations. Show the relational schema design under each of those four options (8A, 8B, 8C, 8D).

Question
All relations should have a name, primary key, attribute(s) as necessary, and foreign key(s) as necessary. Each relational data model must contain relations and should use arrows to represent foreign keys (referential integrity). The ER diagram should include correct notation for entity types, relationship types, attributes, key attributes, and relationship attributes. Cardinality constraints are not needed.
