网上电子广告系统软件的研制

主要探讨了开发分布式应用程序的解决方案，以及建立基于组件三层结构应用的相关技术，其中包括：COM（Component Objects Model）组件模型、IIS（Intemet Information Server）、MTS（Microsoft Transactions Server)、ASP(Active Server Page),ADO(ActiveX Data Objects）等。详细介绍了一个基于组件三层结构的电子分类广告系统，系统服务器端运行于Microsoft Windows2000环境下，使用IS5．0作为Web服务器。客户端可以是任何支持ActiveX技术的浏览器，数据库系统采用的是Microsoft SQL Server7.0，该系统集广告、客户信息管理、网上刊登广告，收费付费自动结算于一体，提供高效、快捷，便利的信息处理与服务。该系统设计基于组件三层结构，易维护，易扩充，具有界面友好、风格独特，使用方便，灵活等特点。

A Net-Based Electronic Advertizing System

Methods of developing distributed applications are discussed in the paper. A coherent technique, which is a three-layer structure based on component, is also discussed. It includes COM (Component Objects Model) ,IIS(Internet Information Server) , MTS( MicrosoftTransactions Server) , ASP( Active Server Page) and ADO( ActiveX Data Objects) . Electronic classified advertisement sys-tem is introduced in detail based on the component and the three-layer structure.The system runs under Microsoft Windows 2000 Server with Internet Information Server 5.0 working as its Web Server. Any browser which is supported by ActiveX can visit this system by the Internet. Database system of this system is based on Microsoft SQL Server 7.0. It can be used not only in Adding, Updating, Retrieving of customers and advertisements, and payment balance, but also on web, and provides manage and service of infomation more efficiently, more speedy, and more facility.Based on the component, the system is designed by using of three-layer structure, which is easy to be maintained and extended. Also it has a friendly interface.
