Hi,

I am working in the assignment and i am confused about the previous step of a use case.

If i have a use case that in the first step the user send any information to system (from a form, i suppose), have i to show the previous steps to load the needed information in that form?

I think that it is valid to do an assumption that previous steps are out of context and that the information it will be loaded somehow. Also i have thought to put a service to load this information, but this service will not have methods in the component diagram. What do yoy think about this?

P.D. I am sorry for my english.

Thanks in advance.

Hi,
I did the same way as you think - I've put into assumptions that the initial view of the use case is already loaded and not covered by the sequence diagram
