In UML modeling, you can create one or several activity diagrams to illustrate how the activity nodes, activity edges, and other activity diagram model elements relate to each other.
Adding call behaviors to activity diagrams
When you model the flow of control in an activity diagram, you can add call behavior nodes that reference behavior that is defined in other diagrams. You can create a reference to behavior in a new activity, state machine, or interaction diagram or create a reference to behavior in an existing diagram.Adding call operations to activity diagrams
When you model the flow of objects in an activity diagram, you can add call operations that reference behavior that is defined by operations in the model. You can create a reference to a new operation or to an existing operation.Adding relationships to diagrams
In UML diagrams, you can add relationships to diagram elements to describe how they relate to each other.
