I am working on a use case diagram for a info management system where users can come and access information about their favorite characters and events and administrators can add/update info. All this info is stored in a database existing in an external cloud based system that provides software as a service. How do I incorporate this system into my use case diagram? Would it be another actor or a use case in my diagram?
I was thinking of adding it as another secondary actor and the use case being it manages the data that is added to the system.
