At its worst business logic can be very complex. Rules and logic describe many different cases and slants of behavior, and it's this complexity that objects were designed to work with. A Domain Model creates a web of interconnected objects, where each object represents some meaningful individual, whether as large as a corporation or as small as a single line on an order form.

合并了行为和数据的领域对象模型

    在最糟的情况下,业务逻辑可能非常的复杂。规则和逻辑描述了行为上许多不同的条件和变化,而对象就是被设计用来解决的这些复杂性的。领域模型创建了一个互相交互对象组成的网,这里每个对象都扮演某个有意义的个体, 这些对象大可以到一个公司,小可以到订单中的一行。
