Figure 4-35 shows an EER diagram for Vacation Property Rentals. This organization rents preferred properties in several states. As shown in the figure, there are two basic types of properties: beach properties and mountain properties. Transform the EER diagram to a set of relations and develop a relational schema. Diagram the functional dependencies and determine the normal form for each relation. Convert all relations to third normal form, if necessary, and draw a revised relational schema. Suggest an integrity constraint that would ensure that no property is rented twice during the same time interval.
