Comparison of UML Sequence Diagrams to Trace Technical Specification Change

摘要

Sequence diagrams are widely used to model the interactions between objects in an information system. This paper presents a method and develops a tool for comparing UML sequence diagrams to facilitate tracing the technical specification change. The change log is generated to report all the affected elements. The traceability graph associated with the new version of sequence diagram is also constructed to illustrate the updated dependency among components. The proposed automation approach would benefit software process improvement for change impact analysis. In addition, the output generated from the implemented system could fasten the tedious documentation chore.
