Poweredby计算机毕业论文网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.....................................................I第1章绪论.................................错误!未定义书签。1.1课题背景及意义·····················································错误!未定义书签。1.2各类网站的现状分析···············································错误!未定义书签。1.3现在的网站存在的问题及应用前景·····························错误!未定义书签。第2章可行性研究及开发的技术支持...........错误!未定义书签。2.1可行性研究···························································错误!未定义书签。2.2三层体系结构························································错误!未定义书签。2.3ASP.NET································································错误!未定义书签。2.4SQLSERVER2000·····················································错误!未定义书签。2.5WEB2.0·································································错误!未定义书签。第3章需求分析.............................错误!未定义书签。3.1开发策略······························································错误!未定义书签。3.2功能需求······························································错误!未定义书签。3.3业务流程······························································错误!未定义书签。3.4数据流图······························································错误!未定义书签。第4章总体设计.............................错误!未定义书签。4.1模块设计······························································错误!未定义书签。4.2数据库设计···························································错误!未定义书签。4.2.1ER图···························································错误!未定义书签。4.2.2逻辑结构设计················································错误!未定义书签。第5章详细设计.............................错误!未定义书签。5.1系统类设计···························································错误!未定义书签。5.2前台主界面···························································错误!未定义书签。5.2.1新闻显示······················································错误!未定义书签。5.2.2发表评论··············································································45.3后台主界面···························································错误!未定义书签。5.3.1添加新闻······················································错误!未定义书签。5.3.2管理新闻······················································错误!未定义书签。结论.......................................错误!未定义书签。致谢.......................................错误!未定义书签。参考文献.....................................错误!未定义书签。附录.......................................错误!未定义书签。网站系统注册登录模块前台后台新闻列表模块文章内容模块评论模块新闻管理模块评论管理模块资源管理模块用户管理模块网站、权限信息管理模块新闻发布情况统计站内搜索模块网站导航模块栏目管理模块图4-1系统模块结构图图5-2网站前台主界面图5-3新闻内容的显示5.2.2发表评论在用户浏览完新闻后，可以对新闻发表评论，如图5-4所示：图5-4发表评论图5-5网站后台管理主界面图5-6添加新闻图5-7管理新闻
