Each instance of the specific classifier is also an indirect instance of the general classifier. 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 classifierPropertiesNameThe name of actor.IDA unique value for identifying the actor.ComplexityA description of complexity of actor.GoalsGoals to achieve by actor.DocumentationDescription of actor.AbstractIf true, the actor does not provide a complete declaration and can typically not be instantiated. UML Use Case Symbols Edraw is an ideal software to draw UML use case diagrams. ExtendDefinitionThis relationship specifies that the behavior of a use case may be extended by the behavior of another (usually supplementary) use case. AssociationDefinitionAn association specifies a semantic relationship that can occur between typed instances. Realization can be used to model stepwise refinement, optimizations, transformations, templates, model synthesis, framework composition, etc.PropertiesNameThe name of realization relationship.SupplierThe element(s) independent of the client element(s), in the same respect and the same dependency relationship. It has at least two ends represented by properties, each of which is connected to the type of the end. More than one end of the association may have the same type.An end property of an association that is owned by an end class or that is a navigable owned end of the association indicates that the association is navigable from the opposite ends; otherwise, the association is not navigable from the opposite ends.PropertiesNameThe name of association.VisibilityDetermines where the association appears within different namespaces within the overall model, and its accessibility.Association End FromThe source of association.Association End ToThe target of association.DocumentationDescription of association.AbstractIf true, the association does not provide a complete declaration and can typically not be instantiated.
In some directed dependency relationships (such as Refinement Abstractions), a common convention in the domain of class-based OO software is to put the more abstract element in this role. An abstract use case is intended to be used by other use cases.LeafIndicates whether it is possible to further specialize an use case. In some cases (such as a Trace Abstraction) the assignment of direction (that is, the designation of the client element) is at the discretion of the modeler, and is a stipulation.VisibilityDetermines where the realization relationship appears within different namespaces within the overall model, and its accessibility.MappingA composition of an Expression that states the abstraction relationship between the supplier and the client. This value is obtained as a result of the execution of the included use case.Note that the included use case is not optional, and is always required for the including use case to execute correctly.PropertiesNameThe name of include relationship.Including CaseReferences the use case that will include the addition and owns the include relationship.AdditionReferences the use case that is to be included.VisibilityDetermines where the include relationship appears within different namespaces within the overall model, and its accessibility.DocumentationDescription of include relationship. and that is just the beginning!

ActorDefinitionAn 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). Besides drawing the diagram, Visual Paradigm allows you to detail document the requirements through the Use Case Description.
