Analysis Diagram

An Analysis diagram is a simplified Activity diagram, used to capture high level business processes and early models of system behavior and elements. It is less formal than some other diagrams, but provides a useful means of capturing the essential business characteristics and requirements. Robustness diagrams, used extensively in ICONIX, can be created as Analysis diagrams.

You generate Analysis diagram elements and connectors from the Analysis pages of the Toolbox.

An Association implies that two model elements have a relationship, usually implemented as an instance variable in one or both Classes.


A Realizes connector represents that the source object implements or Realizes its destination object.


The Representation relationship is a specialization of a Dependency, connecting Information Item elements that represent the same idea across models.
