Abstract :
Legacy systems that were originally developed using the procedure-oriented approach can be reengineered according to the object-oriented paradigm by the process proposed in this paper. Three phases are included in such a process: an object oriented reverse engineering phase, in which an object oriented analysis model of the legacy system is produced by Fusion/RE; a segmentation phase, in which the original code is segmented into object oriented methods, keeping the procedural language; and finally a transformation phase, in which the segmented code is transformed to an object oriented language by the Draco-Puc machine. The application of this process to a real mechanic and electric car repair shop system, with 20000 lines of source code, is described. Samples of the Java code obtained by transforming the original Clipper code are supplied
