It shows how the objects interact with others in a particular scenario of a use case. With the advanced visual modeling capability, you can create complex sequence diagram in few clicks. Besides, VP-UML can generate sequence diagram from the flow of events which you have defined in the use case description.         Actor Definition An Actor models a type of role played by an entity that interacts with the subject (e.g., by exchanging signals and data), but which is external to the subject (i.e., in the sense that an instance of an actor is not a part of the instance of its corresponding subject). Actors may represent roles played by human users, external hardware, or other subjects. Note that an actor does not necessarily represent a specific physical entity but merely a particular facet (i.e., "role") of some entity that is relevant to the specification of its associated use cases. Thus, a single physical instance may play the role of several different actors and, conversely, a given actor may be played by multiple different instances. Since an actor is external to the subject, it is typically defined in the same classifier or package that incorporates the subject classifier Properties Name The name of actor. Documentation Description of actor. Abstract If true, the actor does not provide a complete declaration and can typically not be instantiated. An abstract actor is intended to be used by other actors. Leaf Indicates whether it is possible to further specialize an actor. If the value is true, then it is not possible to further specialize the actor. Root Indicates whether the actor has no ancestors. (true for no ancestors) Business model Set it to make the actor become a "business actor" Attributes Refers to all of the Properties that are direct (i.e., not inherited or imported) attributes of the actor. Operations An operation is a behavioral feature of an actor that specifies the name, type, parameters, and constraints for invoking an associated behavior. Operations here refers to the operations owned by the actor.
