Yes, There is a single entry point for the whole thing.

I'm not sure I understand your answer, I include the first object (not last?) from the standard sequence and just model the extra interactions.

Can I show at which point in the standard sequence the extra interactions take place?

OK,

The sequence diagrams might be in the wrong place, but I was thinking of them as use case realisations. So I will do that.

However my question about sequence diagrams still remains. If I changed to 2 use cases, voice call and automated voice call, can I just model the differences in some way?

The telephone example was ment to simplfy my current problem. (I thought it would be an easy answer!)

I'm *really* modeling  web server software which performs standard processing for each request (such as loading sessions, deserialise objects, queue tasks update logs)

it then performs what ever action is required by the request and then performs the sandard closure tasks (serialise objects etc..)

the standard tasks involve interactions with about 20 objects. So I thought I could wrap this up in a "Handle Request" use case so that I don't have to keep redrawing it when I model the sequence of events for handling each specific request (which I was thinking would be seperate use cases, each including handle request).

So is this possible or am I running off in completely the wrong direction here?

Thomas,

I'm modelling an existing system. I'm using use cases with sequence diagrams to show how the various parts of the system interact in response to given use cases. I'm pretty sure sequence diagrams are correct.

Uml Process / Use Case with Include - How to draw the sequence

Hi.

I'm trying to add sequence diagrams to my use cases. The problem is when you have linked (include / extend etc)  use cases Im not sure how to draw the the sequence diagram, to show some other interactions are taking place.

As an example you could have a telephone call use case. The sequence for this would be along the lines of

1 Lift Receiver
2 Dial
3 Hangup

you could have 2 extensions to this : voice call and automated service.

for voice call the extra events would be
Talk
Listen (if you are polite :-) )

and for automated service the extra events would be
Listen to menu announcement
Dial Options

so my question is, at last, how do I mark on the extended use cases that this event sequence takes place between Dial and Hang up in the base telephone call use case?
