METHODS AND TOOLS OF PROGRAM RENOVATION

Abstract

In many firms 50% and more of software development capacities are absorbed by maintenance tasks. To solve the maintenance problems associated with old programs methods and tools of software renovation have been developed. Beginning with a description of the maintenance problem we depict the components of program renovation (restructuring, reverse engineering, reengineering) and explore the possibilities of tool support. Because methods of object-orientation promise a distinct reduction of maintenance costs in the area of software newdevelopment we propose program renovation with transition in an object-oriented architecture in the framework of an object-oriented reengineering.
