Visio 2016 UML用例图 [英] Visio 2016 UML Use Case Diagram

问题描述

我认为UML用例图形状中的关联和依赖关系没有任何视觉差异。

I do not see any visual difference between association and dependency in UML Use Case diagram shapes.

是否有任何可靠的例子（越复杂越好） 根据UML标准显示如何以及何时正确使用所有这些形状（元素）？

Is there any solid example(the more complicated the better) which shows how and when to use all these shapes(elements) properly according to the UML standards?

推荐答案

嗨伊万，

通常，UML用例图中的关联和依赖关系连接类型在以下场景中使用：

Generally, the association and dependency connection types in UML Use Case diagram are using in the following scenario:

关联：显示演员与
用例的关系。

依赖：表示一个用例依赖于
另一个用例。

Association: Shows the relationship of an actor to a use case.
Dependency: Indicates that one use case has a dependency on another use case.
