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
