Hello Arno, >I do understand the model. However I still have some questions. >The first question is that you have modelled this in the logical view. >I would think it is something for the use case view, to clarify a usecase.
What you have looks good and more elaborate of each activity (as it should be). I had created the activity diagrams under Logical View for no legitimate reason but to merely concentrate on the diagrams themselves - of course, you'd want these diagrams to be under Use Case View. >I wouldn't use the swimlanes for client and server side during requirements. >I don't know anything about client and server application in that stage of >development. As most web developers/producers prefer, data-validation is ideally done on the client-side using Javascript, to avoid one too many trips back to the server and avoiding un-necessary loads on the server. This is why, I also created that ClientSide-validation activity diagram as an alternative. Other than that, if in your activity diagram the "System" is merely an 'early-stage' abstraction of the combined client+server validation, then I understand. >However, I have attached the model I had in mind: >My idea is that the 'check password data' activity in the diagram is >clarified in the documentation of the activity.

While having the low-level detail of the validation process in the activity's documentation field is one way of doing it, but if you wish to take it one step further, you can actually model it visually also internal to one activity- look at the attached model which I made some changes to the one you had sent. Let me know what you think...
