Metodología de reingeniería del software para la remodelación de aplicaciones científicas heredadas. Informe técnico 2004-003

Abstract

Legacy Systems Reengineering has as primary goal to restructure and transform old systems in easier to maintain applications with nicer and more integrated environments that they run in new platforms of hardware/software. We try to give a general view of what is the software reengineering and which are the approaches that can be taken when modernizing a legacy system that has been obsolete as for operability, but of proved efficiency and that maintains its functionality.We show the characteristics of a development process that adapts itself to this type of systems, verified by means of the case of study, the transformation of an application written in an imperative language, no structured, to a new visual and object oriented language, describing the different stages of the methodology applied to a particular case.
