【摘要】 本论文结合实践研究了多层应用体系结构在开发基于Internet/Intranet的企业信息系统过程中的应用；在这种模式下，开发了甘肃武威地区电力局信息管理系统，本系统主要采用了三层应用体系结构，具体形式包括三层C／S结构和B／S结构；分析了甘肃武威地区电力局信息管理存在的技术问题和缺陷，并基于分布式对象技术提出了一种三层信息管理结构，将企业的信息管理分为数据层、业务层和用户层，三层共同组成一个完整的应用；研究了便用 Power Builder 6.5建立分布式应用程序的原理:研究了WEB服务器与Oracle、SQLServer等数据库连接技术，并建立了变电站信息发布系统。更多还原

【Abstract】 In this thesis the mode of Multi-tier Distributed Application Services Suite is studied, whichis used in the implementation of enterprise information system based on Internet/Intranettechnology. Guided by this mode, We developed Gansu province Wuwei Region Electric PowerDepartment Information Management System, which integrates three-tier Client/Server andBrowser/Server. After analyzing the technical problems in this enterprise informationmanagement system, a three-tier management architecture is given based on distributed objecttechnique. In this architecture, some information management is divided into three layers which iscomposed of data layer, business layer and user layer. In this paper, how to develop the distributedapplication with Power Builder 6.5 is discussed. Also, this paper discusses several methods forMicrosoft Internet Information Server access database which is located on the net. At the sametime, we developed the Electric Power Station Information Publishing System.更多还原
