基于Web服务的异构信息系统通信模型研究

石油企业信息化发展过程中,建立了大量的信息系统,但由于缺乏信息模型的标准和规范,造成这些信息系统之间存在兼容性差、信息资源难以交流共享等问题。本文在解析Web服务体系结构的基础上,提出以石油企业信息化标准作为解决互操作的信息模型,基于Web服务技术构建适合石油系统数据资源共享与交互的通信模型,并设计了通信模型的数据交互机制。实践表明,它能够较好地满足信息模型与通信模型间的松散耦合要求。

Research of Communication Model of Heterogeneous Information System Based on Web Services

With the development of enterprise informatization, petroleum enterprise builds many information system. Because of lacking the information model criterion, these system result in some problems, such as poor compatibility and intercommunion among information resource. This paper construes the structure of Web Service technology. Regarding petroleum enterprise informatization criterion as the basic of interoperation information mode, it brings forward a communication model of data resource share and intercommunion of petroleum system based on Web Services technology,and designs mechanism of data intercommunion.The practics indicates that the scheme is able to satisfy the demand of relax coupling between information model and communication model.
