Use the following tips and techniques when you design a UML 2.0
Activity Diagram. Usually you create Activity Diagrams after
State Machine Diagrams. To design a UML 2.0 Activity Diagram,
follow this general procedure: - Create one or more activities.
You can place several activities on a single diagram, or create
a separate diagram for each. Warning: You cannot create nested
activities. - Usually activities are linked to states or
transitions on State Machine Diagrams. Switch to your State
Machine Diagrams and associate the activities you just created
with states and transitions. Tip: After that you can find that
some more activities must be created, or the same activity can
be used in several places. - Switch back to the Activity
Diagram. Think about flows in your activities. You can have an
object flow (for transferring data), a control flow, both or
even several flows in each activity. - Create starting and
finishing points for every flow. Each flow can have the
following starting points: - Initial node -
