Chapter three - OCUP intermediate

Abstract

This chapter focuses on the areas covered in the OCUP Intermediate test, which include structured classifiers; connectable elements, connectors, and connector ends and properties; ports and classes; invocation actions and triggers; and collaborations. It discusses a diagram form that is used to model flows. The activity diagrams of UML 1.x have been widely used in all kinds of domains—business process modeling, systems engineering, and requirements analyses to algorithms. The Intermediate test covers the topics: object nodes, control nodes, activity partitions, structured activity nodes, conditional and loop nodes, and exception handlers. A dynamic diagram form that represents interaction among selected elements is presented. The best-known candidate of interaction diagrams is the sequence diagram. In addition, there is the communication diagram, which was called “collaboration diagram” in UML 1.x, and there are two new diagram forms introduced in UML 2: the timing diagram and the interaction overview diagram. Sequence, communication, and timing diagrams represent different views of the same model. The test for Intermediate certification focuses more on the interaction model than on the interaction model notation.
