Activity elements enable you to describe the dynamics of the system from the point of view of activities and flows between them.

Activities can be stereotyped as a process to display a business process icon; an Activity is some work that is carried out, which might overlap several Use Cases or form only a part of one Use Case.

Send and Receive events are included as triggers.

A Decision element marks a point where processing might split based on some outcome or value.

The Flow relation models an active transition and Synch points are used to split and rejoin periods of parallel processing.

 

The Basic Activity icon adds the Basic Activity Pattern to your diagram as a starting point for developing the diagram (drag the icon onto the diagram to open the Add Pattern <name> to Diagram dialog and click on the OK button).
