Método RSCT reengenharia de software orientada a componentes usando transformações.

Abstract

This project researched a Component-Oriented Software Reengineering Method using Transformations, named RSCT. The researched method extends the RST Method [Fon02a, Fon02b, Fon02c, Fon02d, Fon04], adding resources to treat the component-based reengineering. The RSCT aims to guide the components construction and reuse in the reengineering of legacy systems. The method is supported by two tools: a Software Transformation System, named Draco-PUC and a CASE tool, named MVCASE, and is divided in 4 (four) phases. In Phase 1, Construct Domains and Transformers, it is obtained the domains and transformers used in the legacy system reverse engineering to obtain of Object-Oriented Design. In Phase 2, Obtain Object-Oriented Design, it is obtained the legacy system object-oriented recovered design, using the domains and transformers constructed in Phase 1. In Phase 3, Construct Components, it is obtained the components of the legacy system domain, from the objectoriented recovered designs in Phase 2. With the MVCASE support, the Software Engineering analyses and refines each Object-Oriented design and uses design patterns to construct the components, making them available in a library. Finally, in Phase 4, Reconstruct Systems, the legacy systems are reconstructed from their object-oriented designs, obtained in Phase 2, reusing the components available in the library.
