For example, in Figure 3 the solid diamond indicates that the relationship is a composition — in other words, that instances of the address class can only exist within the context of a person class.

比如，图3中的实心菱形表示这里是组合关系——换句话说，address类的实例只能存在于person类的上下文中。

Thus, the server never does anything more complicated than the simple one-step diamond divergence (modulo some operation composition).

因此，服务器永远不用负责比单步菱形分歧更复杂的问题（操作组合的模型）。
