【摘要】 在信息经济时代,人们越来越关注使用信息技术和全新的管理观念来提高公共机构和政府的业务水平。将信息技术与政府政务工作结合起来,充分利用网络和各种新技术使公众、合作伙伴、供应商以及公共机构工作人员更方便地得到政府信息,并向他们提供公共服务,这样就形成了电子政务(E_Government)系统。 随着电子政务建设的发展,政府对于信息系统决策支持的要求也在逐步提高。电子政务系统在运行过程中会产生大量有价值的数据,对这些数据进行分析就可以得到很多可供领导进行决策参考的数据和指标。为了使电子政务系统的建设具有前瞻性,在构建电子政务基础架构时,应该考虑充分利用数据分析工具来建立和优化政府内部管理系统与决策支持系统,提高政府部门决策的准确性和科学性,使政府为整个社会的发展提供科学的规划和宏观调控。 为了适应电子政务的发展和电子政务对决策支持系统的需求,本文主要进行了以下几方面的研究: 1.用UML描述了基于J2EE的电子政务决策支持系统的设计 统一建模语言(UML:Unified Modeling Language)是一种标准的图形化建模语言,它用模型来描述系统的结构或静态特征、以及行为或动态特征,从不同的视角为系统架构建模。本文利用了UML对电子政务决策支持系统的设计进行了描述。 2.设计模式的研究和应用 设计模式是在软件设计和开发过程中的经验的总结,在面向对象软件设计中合理使用设计模式将会给系统带来良好的结构。在这篇文章中讨论了设计模式的思想和J2EE的WEB层的几种设计模式,这些模式已经被成功地运用在系统设计之中。 3.基于J2EE模式的电子政务决策支持系统应用框架的设计 结合电子政务的具体应用,本文在参考了一些目前流行的J2EE的WEB层设计框架的基础上提出了一种结合多种J2EE的WEB层的设计模式的适合电子更多还原

【Abstract】 In the information era, people pay more and more attention to use the information technology and brand-new management idea to improve the public organization and the government’s professional skill. Combining the information technology with government’s government affairs work, fully utilizing the network and various kinds of new technologies to let the public, cooperative partner, supplier and public organization’s staff member receive government’s information more conveniently, and offering service to them, all this constructs E-government system.With the development of E-Government, the government’s requirement on decision support of information system is higher gradually. It can supply lots of valuable data for government’s decision-making during the running the E-Government system. In order to make the construction of the E-government system perspective, while structuring the basic framework of the E-government, should make most use of the data analysis tool to set up and optimize the administrative system and DSS inside the government, improving the accuracy of the decision-making of government department, so as to make the government offer scientific planning and macro adjustments and controls on development of the whole society.In order to meet the development of the E-government and demand on DSS of the E-government, this thesis has carried on the research of the following aspects mainly1. Use UML for the description of the design of E-government’s DSS system which based on J2EEUnify the modeling language (UML: Unified Modeling Language) is a kind of standard figure modeling language, used for explanation, modeling and establishment documents of object oriented development system. It use models to describes structure, static and dynamic characteristic of system. This thesis has usedUML to describe the design of the E-government’s DSS system.2. Research and application of Design PatternDesign Pattern is the summary of experience for the software design and development. It will bring good structure to the system when we use it rationally during the object-oriented software’s design. This thesis discusses the Design Pattern’s idea and some kind of Design Patterns for J2EE’s WEB layer, which has been used successfully for the design of system.3. Design of DSS’s framework on the basis of J2EE modeThis thesis puts forward one software frame for WEB layer which combining many kinds of J2EE design pattern after has studied many kinds of present prevailing frameworks of WEB layer’s designing for J2EE. This framework will meet the need of E-Government. In order to describe this framework clearly in this thesis the author uses UML’s Sequence Diagram.4. Research for decision support system’s Model Base of EGovernment Effective operation of DSS cannot leave the support of the Model Base. Itdeposits all kinds of decision-making models, these models can carry on analysis prediction appraisal and optimization to the decision-making questions and therefore Model Base and its administrative system are cores of DSS. This thesis put forward a design in which models can be compounded conveniently after discussing the Model Base system. This design used Composition Pattern that a kind of object-oriented Design Pattern, which makes all models have a unified interface so that can be expanded, be make up and be revised conveniently. It is very suitable for the progressive development way to expand progressively of E-government DSS.更多还原
