A Re-engineering Process Model for Single-Machine Legacy Systems based on SOA Architecture
Xiaoqing Li · Journal of Qingdao Agricultural University · 2012
Single-machine systems have difficulties in flexibility,maintenance and information sharing.Because of the high costs and high risks to implement a totally new system,it is urgent to develop an alternative solution.Therefore,this paper presents a re-engineering process model for single-machine legacy systems based on SOA architecture.This process model combines traditional re-engineering model and SSH framework,transforms single-machine legacy systems into Web systems.A case study is given to illustrate the feasibility and effect of the proposed process model.The result shows that the proposed model can be effectively to avoid isolated islands of information,improve inter-platform interaction and reduce the costs and risks of re-development.
