How to draw a Sequence Diagram for a Use Case that <<include>> another Use Case?

Question

我在绘制包括多个用例的用例的时序图时感到困惑，我应该为每个（包括的）用例绘制单独的时序图还是为这些用例绘制单个时序图？

Answer 1

You ran into a common issue with <<include>> or <<extend>> . If any of both is used, the UC must describe the point where that actually happens. And of course you would not need to expand that part. Instead you refer to the description of I/E UCs. This can be done with diagram gates or by re-using activities.
