14. Actors & Entities Business Actor Represents a role played in relation to the business by someone or something in the business environment Business Worker Represents an abstraction of a human that interacts within the system Active Business Entity Represent an object that business workers access, inspect, manipulate, produce, … Provide the basis for sharing Passive Actor Represents someone in a role who interacts with the system Interacts with but have no control over use-cases Entity Represents an object used to model information and associated behavior May be persistent May be active or passive

15. Actors Actors represent system users Interact with but have no control over use-cases Create Actors at Model Level Right click and select New UML, Package Name Actors Right click package and select New UML, Package Name Contact Manager Right click package and select New UML, Actor Name Contact Manager

16. Use-Case Diagrams Use-case diagrams Graphically depict system behavior Present a high level view of how the system is used as viewed from the actor’s perspective. A use-case diagram may depict all or some of the use cases of a system Select the use-case diagram Drag the actor and use-case on to the diagram Create an association between the actor and the use-case Set line style to Oblique

17. Use-Case Diagrams Label to clarify Create alternative diagrams

18. Use-Case Diagrams Complete Use-Case Detail diagrams Illustrate other actors or use-cases used within the context of the incorporating use- case

19. Use-Case Diagrams Define Associations Includes –Used to partition out parts of a workflow for which the base use case only depends on the result, not the method for reaching the result. Extends –Optionally, or conditionally, add a flow to a business use case that is already complete in itself Generalizes –Specialization into one or more child use cases that represent more specific forms of the parent

20. Use-Case Diagrams Complete other use- case diagrams of incorporated use- cases as needed Select diagram Drag and drop model elements from model tree Add labels

21. Use-Case Diagrams The Main diagram Provides an quick overview of the model Use grouping and labels to add context Provides a navigation point for the model Right click actor and use-case and select –Select in Browser

22. Use-Case Diagrams

23. Actors - Detail Select View, Other Windows, Model Documentation

24. Actors - Detail Right click and select Properties Window Select UML section Select Stereotype Add business worker Select Persistence Select Transient

25. Actors - Detail

26. Select UML section Select Multiplicity

27. Actors - Detail Select a multiplicity

28. Actors - Detail Attributes Not typical of actors, but could be use for establishing role profile attributes Select Attribute tab Click Attribute Icon to add

29. Actors - Detail Enter at least Name Enter other attribute values Repeat as necessary Close

30. Actors - Detail Components Not typical of actors, but could be use for establishing role profile attributes Defines attributes derived from other classes

31. Actors - Detail Operations Not typical of actors

32. Actors - Detail Relationships A relationship is a connection between model elements Relationship types are: Associations Dependencies Generalizations Realizations Transitions

33. Actors - Detail Associations An association is a structural relationship showing that objects of one classifier (actor, use case, class, interface, node, or component) are connected and can navigate to objects of another classifier The are numerous association types

34. Uses Association Uses Association shows which processes the actor is involved Right cick and select Properties Window Select UML section Enter Name

35. Uses Association Select End 1 Section Enter Multiplicity Select End 2 Section Enter Multiplicity

36. Uses Association Qualifiers Acts as a constraint Can be at either end of relationship Aggregation Persistence

37. Uses Association
