Evolução de software através de reengenharia: um processo didático

Abstract

This work presents the construction of a proposed process for performing evolution of legacy systems, using the technique of reengineering. Sought in drafting the process create strategies to facilitate the learning of software development practices and the same compatibility with the application practice in the discipline of Software Evolution, offered to students in the sixth semester of the course of Software engineering. The process consists of an initial stage of evaluation of the legacy system under technical and business perspective, with the objective of evaluating the feasibility of realization of reengineering or another legacy systems maintenance strategy. The second step, based on the horseshoe model, is the step where the legacy system analysis, the analysis and design of the new system and the implementation and deployment of the new system. We opted for an incremental approach to the development of the new system evolved, based on the complete development of small increments. The process was applied in the discipline of Software Evolution, in the second half of 2013 school, and used the Sistema de Gerenciamento de Concursos Públicos (GCP) for the execution of the process activities. For the evaluation of the implementation of the process in the discipline it was used a questionnaire consists of questions related to the evaluation of the process and also for questions that evaluated the learning obtained by students through the provision of practical activities in the discipline. The analysis of the results obtained by evaluating evidence that there was a good acceptance of the proposal and that there was coherence of the proposal with the discipline. Additionally, it was noted that there were significant reengineering learning through the provision of practical activities.
