8. Use the dependency diagram shown in Figure P6.8 to work the following problems. a. Break up the dependency diagram shown in Figure P6.8 to create two new dependency diagrams: one in 3NF and one in 2NF. b. Modify the dependency diagrams you created in Problem 8a to produce a set of dependency diagrams that are in 3NF. (Hint: One of your dependency diagrams should be in 3NF but not in BCNF.) c. Modify the dependency diagrams you created in Problem 8b to produce a collec- tion of dependency diagrams that are in 3NF and BCNF. FIGURE P6.8 INITIAL DEPENDENCY DIAGRAM FOR PROBLEM 8 A B D E F G
