Legacy system user interface reengineering based on the agile model driven approach

Abstract

As technologies are continuously evolving, it has become almost mandatory to update and redesign systems to be in flux. Organizations can obtain the most cost-effective and valuable solutions by transforming their legacy assets. Reengineering the Legacy System generally aims to lessen the cost of application maintenance and make the systems more up-to-date and efficient. Thus, we provide an agile reengineering methodology for a Legacy System to smoothly evolve to a new system, and simultaneously, the Model-Driven Approach and Service Oriented Architecture (SOA) are introduced into the reengineering process. The aim of this methodology is to use static and dynamic analysis to model the Legacy System interface. The final output model can assist the model transformation tool to rapidly generate a specific language interface and data service, and then join the UI and data service under SOA. This agile reengineering methodology is a new development process in system reengineering. © 2012 Springer-Verlag GmbH.
