12+ Staruml Sequence Diagram Actor. Learn about sequence diagram notations, how to draw sequence diagrams and best practices to follow. An actor may be considered to play a separate role with regard to each use case with which it communicates.
An actor is behaviored classifier which specifies a role played by an external entity that interacts with the subject (e.g., by exchanging signals and data) when an external entity interacts with the subject, it plays the role of a specific actor. You can find this symbol in the use case diagram section of the toolbox. Semantics an actor defines a coherent set of roles that users of an entity can play when diagram procedure for showing sequence numbers in the diagram in order to show or hide.
