Using Dynamic Information for the Iterative Recovery of Collaborations and Roles

Modeling object-oriented applications using collaborations and roles is now well accepted. Collaboration-based or role-based designs decompose an application into tasks performed by a subset of the applications’ classes. Collaborations provide a larger unit of understanding and reuse than classes, and are an important aid in the maintenance and evolution of the software. This kind of design information is lost, however, at the implementation level, making it hard to maintain and evolve an existing software application. The extraction of collaborations from code is therefore an important issue in design recovery. In this paper we propose an iterative approach which uses dynamic information to support the recovery and understanding of collaborations. We describe a tool we have developed to support our approach and demonstrate its use on a case study.
