Abstract GT-VMT 2001 Preliminary Version Integrating Model Information in UML Sequence Diagrams

In a UML model, different aspects of a system are covered by different types of diagrams. Nevertheless, it is important to provide means to check the consistency and completeness of the UML model. This problem is addressed in this paper by integrating the information specified in class and statechart diagrams into sequence diagrams. The representation as constraints attached to certain locations of the objects lifelines in the sequence diagram allows the identification of gaps and contradictory specifications. Furthermore, dependencies between the sequence diagrams can be investigated based on the previous analysis.
