摘要
随着计算机技术的不断发展,遗产软件在软件生产过程中起着越来越重要的作用。如何积极地利用好遗产软件已经成为目前软件工程中讨论的一个热门话题,国内外科研人员对重构遗产软件已经做了大量的研究并且取得了不少研究成果。文中是一篇关于遗产软件重构技术研究的综述性文章。介始了一些遗产软件系统相关的概念,从整体上对遗产软件重构方法进行了分类,阐述并分析了近年来国内外科研人员就遗产软件重构提出的一些思想、方法及模型,对遗产软件重构技术做了一个总结,并提出了组合Agent-Component(AC)来重构分布异构环境下遗产软件的思想,为解决遗产软件的重构尤其是大型复杂系统的重开发问题提供了一个新的思路和途径。
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.
