Improving maintenance through development experiences.

  An empirical comparison is made between present approaches/tools of software maintenance and development. The conclusion is that development technology is more mature in many aspects, such as automation, formalism, confidence, understanding of original systems and application domain. Aims to improve the weakness of maintenance, a unified re-engineering approach is proposed which is based on a wide spectrum language and a set of formal abstraction and transformation rules. A relevant tool is under construction. Keywords : software maintenance and development, re-engineering, wide spectrum language, formal methods, object oriented, time critical systems.
