There are two general approaches for mapping an association to a set of collections. In Section 10.6.2, we map the N-ary association Statistics to two classes, a simple Statistics class to store the attributes of the association, and a StatisticsVault class to store the state of the links among the association links. In Section 10.4.2, we described an alternative approach where the association links are stored in one or both classes at the ends of the association. In the event associations were stored in both classes, we added mutually recursive methods to ensure that both data structures remained consistent. Use this second approach to map the N-ary Statistics association to Collections. Discuss the trade-offs you encounter and the relative advantages of each approach.
