An approach and an eclipse based environment for data migration

This paper presents an incremental approach to migrate COBOL non decomposable data-intensive applications based on files to a modern relational database management system. This approach has been defined and developed within a technology transfer project carried out in cooperation between the University of Salerno and a small industrial partner. The developed approach first reengineers the original database and then adapts the code of the legacy application to enable the communication with reengineered database. A wrapper enables the communication between the legacy code and the new database. To support the software engineer in the different phases of the defined approach an Eclipse plug-in has also been developed. Finally, both the plug-in and the approach have been assessed on a legacy system of our industrial partner.
