面向服務架構論文：基于SOA的應用集成設計研究【中文摘要】隨著信息技術和網絡技術的發展,出現了各種基于不同平臺的應用系統。對于企業用戶,很容易陷入多種應用系統交織在一起的混亂局面當中,由于基于不同平臺的應用系統之間很難實現信息共享,所以最終導致信息孤島的形成。從企業的現狀來看,對現有應用系統進行集成,可以節約軟件投資,保證現有系統繼續使用,是目前消除信息孤島的最佳途徑。由于傳統的應用集成實現技術存在緊密耦合、交互性差、可擴展性差等不足,本文將面向服務的架構引入到應用系統集成研究中,從面向服務集成的核心技術SOA和Web服務理論入手,按一個SOA項開發流程,分別論述了面向服務的需求分析與設計、面向服務集成的開發及面向服務集成的案例實現。在分析與設計部分,總結了SOA建模的原則和服務建模的過程。在開發部分,設計了一個SOA分層架構模型并對每層開發的服務進行了詳細論述。SOA分層架構的核心思想是運用SOA理論將企業現有的信息系統分解成多個獨立的粗粒度Web服務,信息的集成即變成Web服務之間的交互,從而隱藏了原信息系統的位置和實現技術。Web服務還可進行靈活的組合,形成不同的業務工作流,滿足企業隨需而變的需要,更加突出基于SOA面向服務的集成與平臺無關、易于擴展、易于集成等特點。最后通過冀東水泥企業集成平臺的建設實例分析SOA項實踐。【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.【關鍵詞】面向服務架構 Web服務 應用集成【英文關鍵詞】SOA(Service-oriented architecture) Web service Applieation Integration【目錄】基于SOA的應用集成設計研究摘要4-5ABSTRACT5第一章 緒論8-121.1 論文的研究背景8-91.2 國內外研究概況9-101.3 論文的主要工作101.4 論文結構10-12第二章 SOA 簡介12-272.1 SOA 概述12-162.1.1 SOA 的發展歷程12-132.1.2 為什么需要SOA13-152.1.3 SOA 的概念15-162.2 SOA 的角色關系模型16-172.3 SOA 的基本特征17-192.4 SOA 的優點19-212.5 SOA 與傳統的軟件架構的比較21-222.6 SOA 的相關技術介紹22-252.6.1 ESB22-232.6.2 Web 服務23-242.6.3 BEPL24-252.7 SOA 的發展前景25-262.8 小結26-27第三章 SOA 的實現技術WEB 服務27-413.1 WEB 服務概述27-333.1.1 Web 服務的歷史與現狀29-323.1.2 Web 服務的發展32-333.2 WEB 服務的應用場合33-343.3 WEB 服務技術體系結構34-373.4 WEB 服務組件實現方法37-383.5 WEB 服務與SOA38-393.6 小結39-41第四章 SOA 在冀東水泥項目中的應用41-664.1 基于SOA 的應用集成需求分析41-454.1.1 系統現狀41-434.1.2 系統需求43-454.2 基于SOA 的應用集成設計45-644.2.
