Design And Implementation Of Management Information System Based On SOA

As China's reform and opening-up deepens, traditional industrialization and its extensive development bring about more and more problems, among which are resources exhaustion and environmental issues. Therefore, China is seeking a new type of industrialization whose development depends on accelerating the construction of information system. During the enterprises'information construction, information islands emerge from disconnection between applications made at different times. In addition, the expanding business often requires escalation and improvement on the existing system. Facing these problems, how to effectively integrate the existing enterprise IT systems becomes an important issue to tackle. The key to this issue is Service Oriented Architecture (SOA) which is loosely coupled and independent of the underlying platform.This paper brings up the concept of SOA-based enterprise management IT system after discussing the disadvantages of traditional IT system. The paper also introduces the principles of SOA and its relative technologies. In particular, the paper focuses on the design and realization of SOA-based Management Information system.The contributions of this paper are as follows:(1) After the analysis of SOA, a entire framework of system based on SOA are prompted.The workflow management,device management, materials management,project management,system configure management are developed as separate Web Service to assemble the whole application.(2) Based on the analysis of requirement,this paper illustrates the process of services designning in detail.And it shows the details of database design.(3) Set the process of equipment information query service as a example to explain how to use N-layers service model to fulfill operation module service:user layer,operation interface layer,operation logic layer,and data accessing layer fulfill coarse granularity web service.This paper designed a lightweight SOA framework which based on based on the requirement of medium-sized enterprise.Compared to normal SOA solution, this system, which is has more straightforward function structure, shorter developed circulation and lower cost, and also has nicer maneuverability, maintainability, stability and expansibility.After being tested,it shows the ability of replacing the traditional manual work It can reduce a lot of the executing time and most of contrived mistakes, which enhances the efficiency and assures the quality.
