Transforming Legacy Systems into User-Centred Web Applications
The web revolution makes outdated preexisting Information Systems (legacy systems). Companies need to update their Information Systems without lose neither investments on design and implementation made in the past nor the know-how acquired during years. The modern trend is to activate a reengineering process for the legacy systems. It is important that the reengineering process con-sider both technological aspect and definition of the Human Computer Interaction as important quality factors for the Information System transformation into a Web Information System. The process requires a methodological approach oriented to the application of a specific methodology for each reengineering phase. In this paper, we present a reengineering path that involves both technological and methodological aspects. The idea was born during the MIGR.O.S (MIGRation Open Source) project that aims to transform legacy systems into modern Web Information Systems.
