Creating Harmony-SE activity diagrams

You can create new activity diagrams and sequence diagrams from the initial provided Harmony-SE project, or from another activity diagram. An activity diagram is the specification for its related activity.

About this task

Activity modeling emphasizes the inputs and outputs, sequence, and conditions for coordinating other behaviors, instead of who owns those behaviors. When you create an activity, automatically you create an activity diagram.

Procedure

  1. In Rational® Rhapsody® C++ model, select the package, use case, block or operation that you want to contain the activity, or the activity diagram.
  2. Right-click on the package , use case, block or operation, and select Add New > Diagrams > Activity Diagram.

Results

Rational Rhapsody for C++ then adds both a new activity and, under the activity in the browser, a new activity diagram to the model. It also opens the blank diagram in the drawing area. You can change the default activity name, but not the diagram name. It is useful to immediately show the activity frame using the Show/Hide Activity Frame option. You can access the Show/Hide Activity Frame option by right-clicking on the newly created activity diagram.

Activities specify the following information:

  • Coordination of executions of lower-level behaviors
  • Flow of control
  • Flow of data
