Class diagram to show external systems.

Hi Ranchers,

In my assignment, i need to access Mail server and external webservices. How can i show that in class diagram. From previous posts i found it has to be shown in class diagram.
I read few comments saying failed in class diagram because of incomplete external systems information.

Thanks in advance.

Hi Purna,

Information about the external systems has to be provided in Component Diagram. Minimum information in terms of a method in a class to send an email and to invoke web service method are sufficient in Class diagram. You can also provide more information in assumptions about the interactions with the external systems.

Hi Naresh,

Thanks a lot for your suggestion.

Cheers.
