| Abstract | |
The need to evolve legacy systems has increased significantly with the advent of new technologies. To support this tendency, several reengineering methods have been proposed. However, few have effective computing support, some use design patterns or reengineering specific patterns and none use pattern language-based frameworks. This thesis's theme belongs to the Information Systems domain. An agile framework based reengineering infrastructure is proposed for the legacy system reverse engineering with the support of an analysis pattern language; also provided the understanding and documentation necessary for framework instantiation. The legacy system understanding is also supported by its execution with test cases. These are also subsequently used to validate the target system. The framework, whose construction is based on the analysis pattern language, is used to obtain the target system design and implementation. To allow the reengineering with the infrastructure support, an agile reengineering process has been created. As in software development, a large portion of the reengineering time is spent with VV&T activities. To minimize this problem, a testing reuse approach is proposed in this thesis. This approach aggregates test resources to the patterns of the analysis pattern language allowing reuse, not only of the analysis solutions, but also of the associated test resources. The framework used in software reengineering contributes to its evolution, as the domain to which they belong may evolve, and some of the framework domain requirements might not have been elicited during its development. Thus, in this thesis, a process for application framework evolution is also proposed. The processes and the approach are associated to the infrastructure defined to support its effectiveness. Furthermore, to evaluate the agile reengineering process that provides reuse at several abstraction levels, an experimentation package is also partially defined. Case studies and examples of use have been conducted with the products defined. We stress that other studies have to be done to enable the determination of results with statistical significance.
