Large-Scale Data Reengineering: Return from Experience
Jean Henrard, Didier Roland, Anthony Cleve, Jean-Luc Hainaut · 2008
This paper reports on a recent data reengineering project, the goal of which was to migrate a large CODASYL database towards a relational platform. The legacy system, made of one million lines of COBOL code, is in use in a Belgian federal administration. The approach followed combines program transformation, data reverse engineering, data analysis, wrapping and code generation techniques.
