Dynamic Modeling in Forward and Reverse Engineering of Object-Oriented Software Systems

A prototype tool called SCED is used for modeling the dynamic behavior of object-oriented software as scenario diagrams and state diagrams. In SCED state diagrams can be synthesized automatically from scenario diagrams. When reverse engineering existing software, a parser and a debugger are used for extracting static and dynamic information, respectively. The parsed information is viewed as a nested graph using a reverse engineering environment Rigi. The debugged information is shown as SCED scenario diagrams and state diagrams. Static and dynamic views to the software can be improved and insured by comparing partly overlapping informationgenerated by the parser and the de-
