石油企业信息系统互操作通信模型的构建

随着石油企业信息化进程进一步加快,各个业务系统数据库异构性问题越来越突出。如何有效地利用这些历史数据,集成遗留系统,成为目前集成领域的一大热点。在分析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,较好地实现异构数据源统一透明访问,保证数据完整性、安全性和一致性,并且具有较高的开发效率。

Discussion of Creating Communication Model Based on Oil Enterprise Information System

With the development of oil enterprise informatization,the question of heterogeneous database of each operation system is more and more intractable.It is a hotspot of present integration field on how to use history data integrating old system availably.This paper construes the structure of Web Service technology.Regarding oil 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 practice indicates that the scheme is able to satisfy the demand of relax coupling between information model and communication model,to achieve uniform transparence access of heterogeneous data,to ensure data integrality,security,consistency,and takes on more developing efficiency.
