UML图用例条件 [英] UML diagram use case condition
问题描述
我正在创建用例图。我有两个参与者:用户和管理员。管理员可以检查所有订单,而用户只能检查他/她的订单。
I am creating use-case diagram. I have two actors: user and admin. Admin can check all orders, and user can check only his/her orders.
我应该在UML图中创建两个用例,还是可以将一个用例与用户角色的条件?
Should I create two use cases in my UML diagram, or I can use one use case with condition for user actor?
如果可以使用条件,则必须使用哪个符号?是方括号还是大括号?
If I can use condition, which symbol must I use? Square brackets or curly brackets?
推荐答案
您需要将约束附加到连接器,用例或参与者(其中这是最合适的)。看起来可能像这样:
You need to attach a constraint to either the connector, the use case or the actor (where it's most appropriate). It could look like this:

请注意,这是一个示例,其中包含多余的约束,对于真正的UC不应执行。
Note that this is an example and contains redundant constraints which should not be done for a real UC.
