A Robustness Diagram is basically a simplified UML
communication/collaboration diagram which uses the graphical symbols
The elements of the Component diagram are available in the tool bar:
New actor. This is the same concept as actors in a
UML use case diagram.
New Boundary. This represents software elements such as
screens, reports, HTML pages, or system interfaces that actors interact
with. Also called interface elements.
New controller. This serves as the glue between
boundary elements and entity elements, implementing the logic required
to manage the various elements and their interactions.
New entity. These are entity types that are
typically found in your conceptual model.
New use case. Use cases can invoke other use cases you
need to be able to depict this on your robustness diagrams.
- Actors can only communicate with Boundary classes.
- Boundary classes can only communicate with Control
classes and Actors.
- Entity classes can only communicate with Control
- Control classes can communicate with Boundary
classes, other Control classes and with Actors.
