Creating communication relationships
When finished, you should have a diagram that looks something
like this:
Creating communication relationships
Communications establish relationships between actors and use
cases. A communication can be:
■ A bidirectional communication, in which messages flow both
ways between the actor and the use case
■ A communication from the actor to the use case
■ A communication from the use case to the actor
Now that you’ve created use cases and actors, you’ll want to show
the communication relationships that exist between them. You’ll
begin with bidirectional communications.
