Sequence
Diagram

The Sequence diagram describes
the behavior provided by a system to interactors. The Sequence diagram
models real-time scenarios and complexity, and defines communications
between entities of the system to specify the behavior of the
participants.
The following
concepts can be used to build Sequence diagrams with Open
ModelSphere:
- Actor

- Class Role

- Activation

- Message

creation tool
located in the UML modeling toolbar.
- With the actor
tool selected, click anywhere inside the diagram window.
