From the outside, the Unified Modeling Language encompasses the following models: • Use-case diagrams • Class diagrams • State-machine diagrams • Message-trace diagrams • Object-message diagrams • Process diagrams • Module diagrams • Network diagrams Use-case diagrams look pretty much as they do in Objectory. Class diagrams look much like OMT class diagrams (classes are rendered as rectangles) but with most relationships drawn from Booch. State-machine diagrams, as developed by David Harel, are the same as in Booch and OMT. Message-trace diagrams were in all three methods (and have thus been unified). Object-message diagrams are derived from Booch (with the change that objects are no
