Source code driven decomposition of object-oriented legacy systems a systemic literature review and research outlook

Abstract

Many enterprise applications have been developed over the last three decades therefore known as legacy systems. Usually they are monolith, inflexible, poorly documented and hard to maintain, however they are important to enterprises. The evolution of these systems depends on their decomposability. The purpose of this paper is to summarize existing knowledge, requirements and limitations for object-oriented legacy system decomposition based on systematic literature review. The investigation is performed as a part of the universityindustry collaboration research project.
