4-40. Transform Figure 2-15a , attribute version, to 3NF relations. Transform Figure 2-15b , relationship
version, to 3NF relations. Compare these two sets of 3NF relations with those in Figure 4-10 . What observations
and conclusions do you reach by comparing these different sets of 3NF relations?
