HU Shun-yang · Computer Technology and Development · 2009
With the development of computer technology,the legacy software systems play a more and more important role in software production today.At the same time,how to take the advantages of legacy software systems effectively has become a hot discussion topic in current software engineering and a lot of researchers inside and outside the country have done a number of researches on reconstructing legacy software system.This paper is an overview on reconstructing the legacy software system.Introduces some relative concepts about legacy software system first,then describes the classification of current reconstruction approaches used in legacy software system and analyses these approaches in details.The end of the paper is conclusions on reconstruction of legacy software system and the concept of AC is come up to reconstruct distributed and heterogeneous legacy software systems.It provides a new concept and approach in reconstructing legacy software,especially for those large scale and complex systems.
