Of course, the model also contains many things not synthesized in code that provide a wider context; such as use cases, traceability to requirements, and other key product artifacts.
当然,模型还包含了许多没有同步化的代码,这些代码提供了一个广阔的背景;例如用例,对需求的追踪性,以及其他关键的产品工件。
These use case realizations model how the parts of the system interact within the context of a specific use case.
这些用例实现对系统的一些部分如何在具体用例环境中交互进行建模。
The use case model should place the system in context, showing the boundaries of the system and the external actors as well as describing the key interactions between the system and the actors.
用例模型应该将系统放到上下文环境中,显示系统和外部参与者之间的边界,并描述系统和参与者之间的关键交互。
