Understanding software systems using reverse engineering technology perspectives from the Rigi project

Software engineering research has focused mainly on software construction and has neglected software maintenance and evolution. Proposed is a shift in research from synthesis to analysis. Reverse engineering is introduced as a possible solution to program understanding and software analysis. Presented is reverse engineering technology developed as part of the Rigi project. The Rigi approach involves the identi cation of software artifacts in the subject system and the aggregation of these artifacts to form more abstract architectural models. Reported are some analyses on the source code of SQL/DS, performed by the authors while visiting the Program Understanding project at the IBM Centre for Advanced Studies in Toronto.
