Rational Software Modeler and Eclipse  Development Platform integrated with Eclipse.  Results in a richer and more user- friendly toolset.  Eclipse because of its usability features and development plug-ins.  Different perspectives to allow usage of required features. 2 King Saud University - Introduction to Software Engineering - SWE 211

Perspectives  Modeling perspective: To create and manage your UML assets. Rational Software Modeler allows you to build any UML diagram: ○ Use case diagrams. ○ Class diagrams. ○ Sequence diagrams. ○ Collaboration diagrams, and so on.

Perspectives (2)  Requirements perspective: Modeling the diagrams (Use Case, Class etc.) Allows integration with Rational Requisite Pro.  Modeling perspective: To publish your model so that others can view it. King Saud University - Introduction to Software Engineering - SWE 2114

Simple Use Case Modeling  You can use UML use case diagrams to describe the functionality of a system. Use cases have four major elements: Actors: Interact with the system; typically appear as stick figures in a use case diagram (although this tool shows a graphic that looks like a person) Use cases: Describe the functionality of the system; appear as ovals in the diagram System: The system itself Relationships: Demonstrate the relationships among the above three elements; appear as lines in the diagram King Saud University - Introduction to Software Engineering - SWE 2115
