In addition, the types of actions or styles of activity models might need to be constrained to allow efficient transformation of those models to the target execution platform.

另外，活动模型样式或者操作的类型需要得到限制，以支持那些模型向目标执行平台的有效转换。

We get the structure information of the executable models from the activity models and the binding information from the rule models and the domain information from the data models.

从活动模型中获得可执行模型的结构信息，从规则模型中获得可执行模型的约束信息，从数据模型中获得模型的数据域信息。
