Starting point / Initial Node is shown as A Black Circle shape.
Ending point / Final Node is shown as A Black Circle Inside A White Circle shape.
The Flow Of The Activity / Flow Transition is shown as Single Headed Arrow shape.
- Control Flow is shown as a Solid Line Arrow shape from a source action state to a target action state.
- Object Flow is shown as a Dashed Arrow between an action state and an object.
Activity or Action is shown as Rounded Rectangles shape.
Guard Label / Label Arrow is shown as a Text Inside Angle Bracket.
Control Flow in Activity Diagram consist of:
- Decision / Branches Node is shown as Diamond shape with an incoming edge and presents them to multiple outgoing edges..
- Merge Node is shown as Diamond shape with multiple incoming edges and a single outgoing edge.
Object Node is shown as Rectangle shape.
Parallel Processing: Fork ( the flow of the activity ), Join ( the flow of the activity ), Synchronization Bars.
Parallel Processing consist of:
- Forks are represented by a horizontal or vertical bar ( Synchronization Bars ) with multiple outgoing edges, with each edge leading to a different activity node.
- Join are represented with the concurrent flows merge back as a a single flow of control into a horizontal or vertical bar ( Synchronization Bars ) .
- Synchronization Bars are represented by the heavy horizontal or vertical Solid Line shape.
- Paralel Activity / Concurrent Threads Of Control is represented by Rounded Rectangles shape.
Parallel Processing functions consist of:
- Modeling Parallel Processes.
- Resource Allocation.
- Workflow Management.
- Load Balancing.
Partitions / Swimlane Heading is shown as Labeled Text Inside A Rectangle shape at the top / left with the element responsible / role responsibilities.
Swimlanes has the visual similarity between the horizontal rows / vertical columns of the diagram to that of the swimlanes found within a swiming pool. Swimlanes is shown as a visual region separated from neighboring swimlanes by vertical / horizontal solid lines on both sides and labeled at the top / left with the element responsible for action states within the swimlane.
