A reengineering process for migrating from an object-oriented legacy system to a component-based system

Abstract

Computing environments are evolving from mainframe systems to distributed systems. Stand-alone programs that have been developed using object-oriented technology are not suitable for these new environments. However, programs that have been developed using a component-based technology have proven to be more suitable for the new environments due to their granularity and reusability. In this paper, we present a reengineering process for migrating from an object-oriented legacy system to a component-based system. This process consists of two steps: first, to create basic components with the relationship of their constituent classes, second, to refine components using the metrics we propose.
