4-44. 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.
1. The BOOK CHECKOUT relation stores data about books checked out by students at a university. The functional dependencies are given below for this relation. a. Which normal form is this relation in and why? b. Using the normalization steps develop a set of 3NF relations for this view. Describe the relational schema for the 3NF relations that you developed. Be sure to list the referential integrity constraints BOOK CHECKOUT (StudentID, StudentName, StudentPhoneNumer, ISBN, BookTitie, CheckOutDate, ReturnDate) StudentID > StudentName, StudentPhoneNumer ISBN -> BookTitle StudentiD, ISBN ->CheckOutDate, ReturnDate
Using the STUDENT table structure shown in Table 1, do the following: a. Write the relational schema and draw its dependency diagram. Identify all dependencies, including all transitive dependencies. b. Write the relational schema and draw the dependency diagram to meet the 3NF requirements to the greatest practical extent possible. If you believe that practical considerations dictate using a 2NF structure, explain why your decision to retain 2NF is appropriate. If necessary, add or modify attributes to create appropriate determinants and to adhere to the naming conventions. c. Using the results of Problem b, draw the Crow's Foot ERD.
