文档介绍：基于面向服务架构的电力企业应用集成
摘要
随着信息化的发展,应用系统的集成问题越来越受到人们的关注,企业要求针对其业务过程对信息进行整合管理,分布式异构系统的集成问题是企业应用集成要解决的关键问题。传统应用集成由于实现技术在异构平台互操作、接口统一描述等方面存在局限性导致集成系统缺乏动态可扩展性,异构平台间的互操作性差,且无法摆脱技术厂商及应用环境的限制,因而企业应用集成的目标很难实现。面向服务架构(Service Oriented Architecture,SOA)的提出为企业应用集成提供了一种动态、可扩展的架构方案。Web Services的逐渐成熟化为SOA以及企业应用集成提供了技术支持。
本课题首先在分析传统企业应用集成解决方案不足的基础上探讨了SOA,分析了SOA的实现关键及实现方式,在此基础上给出了以Web Services作为实现技术的“Web Services+SOA”的面向服务应用集成方案,设计了以Web Services为基础的面向服务集成框架,并分析了面向服务集成软件的层次结构,最后结合某电力企业调度系统的实际情况,引入了SOA的思想到其应用集成中,通过实验系统的开发,验证了解决方案的可行性。

THE APPLICATION INTEGRATION OF POWER ENTERPRISE BASED ON SERVICE-ORIENTED
STRUCTURE
Abstract
With the development of / and the distributed systems increasing,the application system integration is sharing us in the face. But traditional Enterprise Application Integration(EAI)has not only a great way to dynamic expansibility and interoperating in isomer us systems but also been restricted by technical manufacture and application environments which is caused by the realization technology localization in interoperation,unification description of interface and loose couple etc. Service-Oriented Architecture (SOA) is brought forward by Gartner Group. And with Web Service’s development and maturation,SOA has realization technology support.
Based on analyzing the shortage of traditional EAI resolvents,SOA is described in this paper. And the realization modes and key of SOA are also "Web Services+SOA"is put forward as the optimal resolve for EAI in actual technology level. Next the author designs the services-oriented application integration system framework which is realized with Web Services. And system’s hierarchy is also analyzed from software point of view.
