A reverse engineering method and experiences for industrial COBOL system

One of the most important things in restructuring current system is to clarify business specification which are implemented in the current system. Reverse engineering technology, which extracts reusable business specification from a system, is very effective for this purpose. We have developed DORE (Data Oriented Re-Engineering), a re-engineering methodology for system restructuring, and tools that support reverse engineering. By using these methodology and tools, it becomes possible to extract business specification which should be implemented in the new system, from the current system. In this paper, we present the re-engineering methodology and tools, and introduce a case study in Kawasaki Steel Corporation, in which those methodology and tools are used
