基于SOA的制造企业信息系统集成模型研究

Integration of Enterprise Information Systems Based on Service Oriented Architecture

随着计算机辅助管理系统在制造企业的大量应用,为企业提升信息化水平的同时也带来了"信息孤岛"问题。如何对这些系统进行有效集成成为一个重要问题。本文对国内外学者在信息系统集成方面的研究做了分析总结,在此基础上提出基于面向服务架构的信息系统集成模型。该模型包括界面层、总线层、服务层、数据层四层体系结构。给出了该集成体系的信息访问模型和网络集成模型,介绍了其信息交互机制。最后,对集成过程中集中权限管理、元数据适配、可重构的服务、多服务运行机制等关键技术进行了详细阐述。

Currently,many manufacturing enterprises tended to use computer aid system to improve their work efficiency. However,these systems which developed by different companies with different ways will bring＂isolated island of information＂problem.How to integrate these information systems effectively becomes an important problem. In this paper,an integration model based on Service Oriented Architecture is proposed,which includes four layers： presentation layer,bus layer,service layer and data layer.Information interaction model and network integration model are discussed. At last,several key technologies of the integration model,which manly contain centralized authorization management,metadata adaptation,reconfigurable services and multi service operating mechanism,are also introduced.
