  2. Outline • Setting up RSM environment • Activity Diagram • Use-case Diagram • Class Diagram • Sequence Diagram • Archiving

  3. RSM Environment • Built on Eclipse environment • Workspace • Modeling perspective • Comes with Eclipse 3.2 • Or installed as Eclipse plug-in • Note: on Windows 7, use your own version of Eclipse and JDK/JRE • Download Eclipse 3.2.2 and latest JDK/JRE • Choose “Extend Eclipse”

  4. Activity Diagram • Captures a sequence of activities and actions • In CSCI577, used to model business workflow or business process

  5. Components • Partitions • Actions • Control node (i.e. decision node) • Control flow • Transfer of action • Object node (i.e. data) • Object flow • Transfer of object

  6. Steps • Create a new model called “Activity Model” • Right click on the model • Add Diagram  Activity Diagram • On the right panel, select the following • Partition • Actions • Control node (decision node) • Control flow

  7. Use-Case Diagram • Captures the interaction between actors and system • Shows the possible capabilities/functionalities the system can perform • Association • Roles and multiplicities do not apply

  8. Components • Actor • Show the hierarchy of users • Use-case • The actions that user can perform • Relationships • Association • Dependencies • “Includes” • invocation of a use case by another one • “Extends” • Ultimately an alternate course of action • Should avoid as it complicates the model

  9. Steps • Create “System Analysis” model • Right click on the model • Add Diagram  Use-case Diagram • Add an actor • Add a few use-cases • Association from actor to use-case • “Include” relationship from 1 use-case to another • Right vs. wrong • User inheritance (super user)

  10. Class Diagram • Detailed designs of the classes • Contains • Attributes • Operations • Relations between classes

  11. Components • Classes • Boundary: pages, view • Controller: logic • Entity: model, data • Relationships • Association: “Has-a” • Aggregation: “Part-of” • Composition • Stronger aggregation • Lives and dies with parent

  12. Steps • Create a new model called “Design Model” • Create a package called “Design Classes” • Add new classes: • <<boundary>> VolunteerPage • <<controller>> TimeController • <<entity>> Time • <<entity>> TimeSheet • <<entity>> VolunteerProfile • Create relationships • Composition • Specialization • Association

  13. Sequence Diagram • Captures the detailed sequence of operations when a use-case takes place • Includes: • Actors • Components • Classes • Hardware • Software

  14. Steps • Create a package called “Sequence” • Right click on the model • Add diagram  Sequence diagram • Sequence diagrams are part of “collaboration”. Each collaboration should be named according to the use-case • Different ways of creating “life-line” entity • Select from existing • Create new object • Unspecified (defined later by drag and drop)

  15. Archiving • Archiving the model to be transferred to different computers • Share among team members • Submission • Export as a RAS Asset

  16. Steps • Go to File -> Export • Choose RAS -> RAS Asset • Choose the location to save the file • Choose the project to export • Make sure that the option “Export as complete Eclipse project” is checked
