Activity Diagram - Start and Final Notations

This section describes the Start Notation and the Final Notation used in a UML Activity Diagram. A Start Notation and a Final Notation represent a starting point and an ending point of an action execution sequence within an activity.

Start and Final Notations are graphical notations used in a UML Activity Diagram to represent the starting point and the ending point of an action execution sequence within an activity.

A Start Notation is drawn as a small solid circle.

A Final Notation is drawn as a small solid circle enclosed in an outer circle.

For example, the starting point and the ending point of a simple order processing action execution sequence
can be drawn as a Start Notation and a Final Notation in a UML activity diagram as shown below:

Note that in some UML drawing tools, Start Notation and Final Notation are called Initial State notation and Final State notation
