面向服务架构论文：基于SOA的应用集成设计研究【中文摘要】随着信息技术和网络技术的发展,出现了各种基于不同平台的应用系统。对于企业用户,很容易陷入多种应用系统交织在一起的混乱局面当中,由于基于不同平台的应用系统之间很难实现信息共享,所以最终导致信息孤岛的形成。从企业的现状来看,对现有应用系统进行集成,可以节约软件投资,保证现有系统继续使用,是目前消除信息孤岛的最佳途径。由于传统的应用集成实现技术存在紧密耦合、交互性差、可扩展性差等不足,本文将面向服务的架构引入到应用系统集成研究中,从面向服务集成的核心技术SOA和Web服务理论入手,按一个SOA项开发流程,分别论述了面向服务的需求分析与设计、面向服务集成的开发及面向服务集成的案例实现。在分析与设计部分,总结了SOA建模的原则和服务建模的过程。在开发部分,设计了一个SOA分层架构模型并对每层开发的服务进行了详细论述。SOA分层架构的核心思想是运用SOA理论将企业现有的信息系统分解成多个独立的粗粒度Web服务,信息的集成即变成Web服务之间的交互,从而隐藏了原信息系统的位置和实现技术。Web服务还可进行灵活的组合,形成不同的业务工作流,满足企业随需而变的需要,更加突出基于SOA面向服务的集成与平台无关、易于扩展、易于集成等特点。最后通过冀东水泥企业集成平台的建设实例分析SOA项实践。【英文摘要】With the development of information technology and network technique, various of application systems based on different platforms appear. For enterprise, it is very easy to fall into the confusion of interlacing with many application systems. Information sharing among the application systems based on different platforms is hard to implement, thus, the solitary information island is formed inside enterprise. Integrating the different types of application systems is the best way to eliminate solitary information island at present, because the existing systems can be used continuously and the investment in them can be saved.Aimed at the traditional integration techniques shortages which are tight coupling, bad interactivity and bad extendibility, this thesis introduces SOA (Service-Oriented Architecture) into the studies of application systems integration. It starts with the core technique of SOA and the theory of web service, analyses the demand of service oriented, and discusses the design, exploitation and case realization of SOA. In the part of analysis and design,it summarizes the SOA modelling principle and the service modelling process.In the development part,it designs a SOA lamination construction model and carries on the detailed elaboration to each development service.This core thought of the architecture is using the SOA theory to decompose the enterprise existing information systems into a number of independent coarse granularity web service.Web information integration namely turns between the web service interactive,thus the original information system position and the realization technology are hidden.The web service also may carry on the nimble combination,forms diversified business work flow,satisfies the enterprise along with the need which must change,illuminates the traits of SOA,such as platform independently、extendible and integration easily.Finally, this thesis introduces the SOA project practice about Enterprise Integration Platform construction for Ji Dong Co.,Ltd as an example.【关键词】面向服务架构 Web服务 应用集成【英文关键词】SOA(Service-oriented architecture) Web service Applieation Integration【目录】基于SOA的应用集成设计研究摘要4-5ABSTRACT5第一章 绪论8-121.1 论文的研究背景8-91.2 国内外研究概况9-101.3 论文的主要工作101.4 论文结构10-12第二章 SOA 简介12-272.1 SOA 概述12-162.1.1 SOA 的发展历程12-132.1.2 为什么需要SOA13-152.1.3 SOA 的概念15-162.2 SOA 的角色关系模型16-172.3 SOA 的基本特征17-192.4 SOA 的优点19-212.5 SOA 与传统的软件架构的比较21-222.6 SOA 的相关技术介绍22-252.6.1 ESB22-232.6.2 Web 服务23-242.6.3 BEPL24-252.7 SOA 的发展前景25-262.8 小结26-27第三章 SOA 的实现技术WEB 服务27-413.1 WEB 服务概述27-333.1.1 Web 服务的历史与现状29-323.1.2 Web 服务的发展32-333.2 WEB 服务的应用场合33-343.3 WEB 服务技术体系结构34-373.4 WEB 服务组件实现方法37-383.5 WEB 服务与SOA38-393.6 小结39-41第四章 SOA 在冀东水泥项目中的应用41-664.1 基于SOA 的应用集成需求分析41-454.1.1 系统现状41-434.1.2 系统需求43-454.2 基于SOA 的应用集成设计45-644.2.
