基于Web服务的电子政务系统的研究与实现
|
摘要
电子政务是政府部门办公事务的网络化和数字化。它以其丰富的信息资源、高效的行政管理模式越来越受到人们的普遍关注,并已成为整个信息化的关键。运用现代计算机和网络通讯技术,将其内部和外部的管理和服务职能通过精简、优化、整合、重组到网上实现,打破时间、空间分隔的制约,为社会公众以及自身提供一体化的高效、优质、廉洁的管理和服务。电子政务的内容广泛,包括了教育、就业、医疗、电子采购、社会保险、企业服务、税务等领域的政府电子服务,而且还要求集成政府各部门的门户网站,导致存在统一标准、信息孤岛和互操作问题。
Web服务提出了一种新的分布式环境中应用系统的集成模式,并基于XML标准定义了一组简单、开放的协议规范。它的主要目标就是构筑一个通用的平台无关、语言无关的技术层,以实现各种异构平台上的应用间的互连互通。Web服务允许在Web站点上放置可编程元素,可实现基于Web的和基于三大核心技术SOAP、WSDL和UDDI的分布式计算和处理。
本文首先介绍了电子政务的研究和发展的现状,分析了电子政务系统建设中存在的问题,并研究了电子政务系统的设计目标。为了解决电子政务信息在政府内部及政府之间的共享问题,本文提出了一种基于Web服务的电子政务系统的设计方案。利用Web服务的平台独立性,松散耦合性等特点,将基于Web服务的电子政务系统与政府内部应用程序进行集成,并且与外部其他政府部门进行协同合作,实现信息共享。通过分析Web服务实现信息流通与共享的关键技术,设计了一个基于Web服务的电子政务系统平台模型。
As networking and digital services of government, e-government gets more and more attention for its wealth of information resources, the efficient mode of administration, and has become the key of information technology. Using modern computer and network communication technology, its internal and external management and service realized in the web by streamlining, optimizing, integrating, restructuring, to break the time and space constraints, providing an high-performance, high-quality, honest management and service for the public and itself. E-government has a wide range of covers, including education, employment, health care, e-procurement, social insurance, business services, taxation and other areas of e-government services, but leading to uniform standards, the information silos and interoperability issues.
Web services presents a system integration model based on a new distributed application environment, and defines a set of simple, open protocol specification based on XML standard. Its main goal is to build a common, platform-independent, language-independent technology layers in order to achieve the application of interconnection among several of heterogeneous platforms. Web services allow the Web site to place programmable elements, enabling Web-based distributed computing and processing, and based on three core technology, SOAP, WSDL, and UDDI.
This thesis firstly introduces the research and development status of e-government, analyzing the problems existing in the construction of e-government, and studying the design goals of e-government system. To address the sharing problem of e-government information between the government and the e-government, this thesis presents an e-government system based on Web services. Using advantages of Web services, such as platform-independent, loosely coupled nature, e-government systems based on Web services integrated with applications within the Government, and collaboration with other external government departments to achieve information sharing. By analyzing the flow of information and sharing technologies of web services, we design a model of e-government platform based on Web- service.
