问题描述
我该如何表示一个图表,其中几个参与者可以访问相同的功能或用例,但是如果我只是在其中扩展,则其中的一些参与者可以在其中使用其他功能或扩展(如果正确的话)。主要的用例意味着每个人都可以访问它?
当用例扩展主要用例时,扩展指向主要用例,可以有条件。作为条件,您可以指定特定的参与者。
如果可以概括参与者,我也已经看到了这种解决方案。但是我更喜欢第一个,因为我不确定它在技术上是否正确(正如您所指出的,扩展用例默认情况下每个人都可以访问)。
希望这会有所帮助。
How can I represent a diagram in which several actors have access to the same function, or "use case" but some of them have additional functions or "extends" (if im right) inside it, if i just extend on the main "use case" that would mean its accessible by everyone right?
When a use case extends the main use case, extension points at the main use case, can have conditions. As a condition you could specify a specific actor.
If the actors can be generalized, I have seen this solution too. But I prefer the first one because I am not sure if it is technically correct (As you noted, extend use case is by default accessible by everyone).
Hope this helps.
这篇关于用例图:用例的几个参与者,只有一些可以访问扩展用例的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
