Virtualization of the entity lifecycle through Object Flow Diagrams, a basic model that captures both events and state transitions, is critical in this model.
使用对象流图(它是捕获事件和状态转换的基础模型)虚拟化实体生命周期是这个模型的关键。
Each event represents a change in state, and the ordered sum of all normal entity states represents a lifecycle.
每个事件代表状态中的一个变化，所有普通实体状态的有序和代表了一个生命周期。
When a customer changes the order or when the business changes a price, we cannot consider these actions part of the normal flow, so they are not associated with the entity (such as order) lifecycle.
当一个用户变更订单或当企业改变价格时，我们不能认为这些动作是正常流程的一部分，因此它们与实体(如订单)的生命周期无关。
