Re-engineering of large scale legacy systems based on frameworks, distributed components and design standards


This research project offers an approach to technological evolution to rebuild legacy systems with recurring bases and on a large scale, aiming to meet the growing demand from businesses and governments that need to upgrade their software and hardware platforms. This approach was structured on a robust software architecture base consisting of distributed components, design standards and frameworks. The defined architecture allows for the technological evolution of the rebuilt systems, since it improves the quality of the code, makes future maintenance easier and permits the running of these systems on heterogeneous, distributed and open platforms. The Catalysis method is used in the development of the components; the principal mechanisms for executing this approach are a transformation system, a support tool for reverse engineering and a Case tool.
