Actors are the users of the system being modeled. Each Actor will have a well-defined role, and in the context of that role have useful interactions with the system.<br/><br/>A person may perform the role of more than one Actor, although they will only assume one role during one use case interaction.<br/><br/>An Actor role may be performed by a non-human system, such as another computer program.<br/>
