From COBOL to SQL through program transformation and XML

By F Meziane and J Aliwa


The cost of maintaining legacy software systems has spiralled and\ud their maintenance became a burden for many organisations. In this\ud paper we present the first prototype of the LOBS-COQ system\ud that attempts to transform COBOL legacy systems into relational\ud database schema and produce SQL statements for data querying.\ud The approach first transforms the COBOL source code into XML\ud files, which are then processed to create tables and develop SQL\ud statements. Frames are used to develop the SQL statements.\ud COBOL statements are parsed and the information extracted is\ud used to fill the frames’ slots
