Software reflexion models bridging

Bridging the gap between source and highlevel models by gail c. Bridging the gap between source and highlevel models software migration and reengineering techniques. We have developed the software reflexion model technique to help engineers perform various software engineering tasks by exploiting rather than removing the drift between design and implementation. Software engineers often use highlevel models for instance, box and arrow sketches to reason and communicate about an existing software system. Reflexion project aims at supporting the emerging hightech industry paradigm shift from selling boxes to supporting integrated solutions, by using operational data to improve the development lifecycles, maintenance and.

A popular approach for coping with this problem is reflexion modeling which usually compares an abstract model of the code with the architecture model. Bridging the gap between source and highlevel models has been selected to receive a 2011 sigsoft retrospective impact paper awards. One problem with highlevel models is that they are almost always inaccurate with respect to the systems source code.
