1) Consider the relation A, with key and functional dependencies shown below. I. What Normal form is A in right now? Why? II. III. What actions would you take to normalize A to the next higher normal form (describe the steps)? Follow those steps you mentioned in the prior question to normalize A to the next higher normal form. Be sure to show all work. IV. V. Once you have normalized A, what normal forms are each the two new relations in? Why? If any of the remaining relations are not in 3NF, normalize them to 3NF. Be sure to show all work.
