Service-oriented reengineering process of legacy system

Reengineering the legacy system into the service-oriented system is the trend of software technological development.However,the existing software process can not perfectly solve the problems facing by service-oriented reengineering,for instance,how to coordinate the communication between the stake holders in the legacy system and process the change in demand rapidly and effectively,how to realize service to meet the requirement of target system structure in flexibility,how to reduce the risk caused by the reuse of legacy system and how to decrease the mistakes of software after the delivery.In order to get over these insufficiencies,this paper designed the service-oriented reengineering process of legacy system(SORP) and explicated the roles,activities,work products and rating methods in the reengineering process.SORP not only integrates the discipline and agility of traditional software process,but also adds some special schemes in accordance with the characters of service reengineering project.Therefore,it may play a guiding role in the practical work of the service-oriented legacy system reengineering.The practice shows that SORP can improve the flexibility of target system′s architecture and reduce the risk of reusing legacy systems.
