A Model-Driven Approach For Information System Migration

In 2002 and 2003, the TRAMs project, led by a consortium of French companies and universities, experimented the application of emerging model engineering techniques to Information System (IS) migration. The main objectives were to define a methodology and to specify an open and modular migration framework to solve IS migration complexity on the basis of models and meta-models, as well as model transformation. A concrete result of this project was the development of a demonstrator that performed the migration of a large COBOL legacy application of an insurance company to use a JAVA and HTML based interface. In this migration use case, we used a common intermediate meta-model based on ISO/RMODP (Reference Model of Open Distributed Processing) extended with the UML Action Semantics formalism. Keywords—model driven architecture, modeling, meta-modeling, model transformation, Information System migration, legacy code.
