中国热载体加热技术的网站建设--新闻系统及页面设计摘要新闻系统与前台页面是每一个成功网站必不可少的元素。新闻系统是比较常见的一种网络站点应用，用于获取，添加、审核、修改、删除新闻等。此外，新闻系统还可以通过提供新闻服务的方式，把系统中的新闻提供给用户或其他站点。本网站在分析现有各类网站的结构的基础上，利用C#作为服务器脚本语言，采用ASP.NET内核制作,采用SQLSERVER2000数据库来储存各种数据。整个系统应用三层体系结构来把用户界面、业务逻辑、数据信息分离开来，结构清晰合理，易于维护，安全性好。应用系统流程图、数据流图、数据字典、ER图清析的展示了整个系统的设计过程。网站前台包含一般网站的用户管理、新闻发布、评论系统、图片和文件的上传与下载、站内搜索等常见功能，让所有访问者能尽快地找到自己需要的信息。后台管理功能强大，运行速度快，对搜索引擎的支持好，界面美观，操作方便，让管理者能方便地管理大量的数据，体现新闻的实时性。关键词：新闻系统，C#，ASP.NET，SQLSERVER2000ABSTRACT目录摘要.......................................................IABSTRACT....................................................II第1章绪论.................................................11.1课题背景及意义·············································································11.2各类网站的现状分析·······································································11.3现在的网站存在的问题及应用前景·····················································3第2章可行性研究及开发的技术支持...........................52.1可行性研究···················································································52.2三层体系结构················································································52.3ASP.NET·······················································································62.4SQLSERVER2000·············································································72.5WEB2.0·························································································8第3章需求分析............................................113.1开发策略·····················································································113.2功能需求····················································································123.3业务流程····················································································143.4数据流图····················································································15第4章总体设计............................................174...
