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.

i have implement video collection website users of specific isp. site hosted on public web-server movies hosted on local isp server. user of isp + general visitors can see available movies; isp's users able play them. player on site point url of local machine ( http://192.x.x.x/movies/mymovie.mov ) private class (192.x.x.x) accessible isp user. question: possible phpmotion script? or need custom work. if possible, can please suggest available mods? phpmotion require modifications able handle this. uploading, conversion, thumbnail generation, , playback pretty static in phpmotion. really though, rather modding entire upload , conversion process, if created quick custom form add entries phpmotion database (maybe include thumbnail upload), tweaked playback paths, should go on phpmotion side of things. assume had videos in format player handle (such flv or mp4).
