UML Uses case Actor choice -

-

i'm working on dashboard project. i'm using uml modeling. first task use case diagram.

the clasic actor has 1 action requesting data wants. work done application. how model in uml use case ?

  • an actor can have 1 or many use cases connected him. number not limited.
  • yes, every use case=behaviour realized application, or uml standard names it, subject (of project).
  • in use case diagram subject defined behaviours. simplest form of use case diagram has no actors, ovals of use cases , nothing else. should name behaviours/actions of system. list, in graphic form. further steps not necessary.
  • you define different kinds of users system , say, users can use actions. starter better stop here. or, @ least, create more thorough use case diagrams other ones.
  • some actions connected including or extending dependencies.
  • the next step joining use cases in groups , name them subsystems. not mix them real sw or hw components! become such, you'll decide later.
  • the next step including elements of other diagrams or whole other diagrams in use case diagram. state machines first candidates.
