询问一些关于UML、Use Cases的问题最近要用J2EE做一个论坛的Project。在Use Cases Analysis的时候遇到了些麻烦。

对于一些Even Trigger的事件，

例如，假设一个用户收到了个短消息，会有一个友好的信息pop-up，提示他收到了来自别人的短消息。然后他点击pop-up的提示，就可以查看短消息。有点类似于MSN提示的功能。

这种情况也是actor和system交互的功能，所以算做use case。

那么在具体写use case step的时候，怎么处理呢？ [御月样 (9-3 10:46, Long long ago)] [ 传统版 | sForum ][登录后回复]1楼

i think it's just the usual case diagramactor A sends a message to system

system forwards the message to actor B

actor B responds[SmellsLikeTeenSpirit (9-3 18:31, Long long ago)] [ 传统版 | sForum ][登录后回复]2楼
