Aspect-Oriented Architectural Analysis using Multi-level Modeling of Complex Systems

摘要

We have shown how REACT's aspect-oriented architectural assessment approach is being applied to support architectural informational shortfalls frequently encountered in modeling large complex systems. The magnitude of the number of classes and methods and their complex interactions requires automated techniques to understand their behavior and identify architectural flaws early. With spiral development cycles requiring frequent revisions to UML architectures, it is necessary to provide flexible techniques that can perform analysis over evolving architectural designs. We have shown how missing behavioral information can be identified and provided with default behavior that can later be refined automatically. With REACT's aspect-oriented approach, aspects can be written to identify architectural sites of interest and either modify, augment or map modeling information so that static and dynamic assessments can be made. REACT's automated translation and simulation of sequence diagrams permits different levels of modeling granularity. REACT's internal management of this model information minimizes the amount of manual intervention required and permits the reuse of prior data over those portions of the architecture that have not changed.
