In that way, it is advantageous to share information and reduce the workload of managers. It will make the document management more scientific, more standard and much safer. Therefore, it is very essential to design a safe network file management system. Online file virtual management system is developed by the SQL Server server and ASP.NET technology in the environment which is Composed of a combination of Visual Studio 2010 integrated development environment and database software SQL Server 2008. According to the demand of the system on-line file virtual management system, it mainly has the file management and file management functions of the two. This system has realized the mobile office, meeting the needs of users in any place and time for personal file upload, download, delete the folder, and new operational changes demand, and realizes the remote data sharing, the Internet into a system can be quickly shared resources edge. After two months of hard work, to modify and improve the system step by step, system has been basically can effectively accomplish its intended function. keywords: Upload, Download, Database, File Management , 目 录 1绪论 4 1.1 课题背景 4 1.2 国内外研究现状 4 1.3 课题研究内容 5 1.4 相关知识概述 5 2 可行性分析 10 2.1 技术可行性分析 10 2.2 经济可行性分析 10 2.3 实施可行性分析 11 3 需求分析 5 3.1 总体需求分析 5 3.2 系统其他需求分析 7 4 系统设计 11 4.1 功能设计 11 4.2 界面设计 12 5 数据库设计 12 5.1 概念结构设计 12 5.2 物理结构设计 12 5.3 数据库实现 14 6 系统详细设计及实现 13 6.1 系统总体概况 13 6.2 系统总体功能设计 13 结束语 15 致 谢 16 参考文献 17 附 录 18 附录A 主要源程序 18 附录B 用户手册 26 附录C 软件光盘 35 附录D 科技译文 36 1绪论 1.1 课题背景 在可以用户互联网登录网站进行信息数据上传、下载、共享等操作。电子邮箱所提供的附件功能是最早的，随着空间的增大，附件功能分成。不管是由于学习或是工作，又或是生活娱乐需求，很多人都会将自己的文件做一个存储备份但是，移动硬盘携带麻烦 1.2 国内外研究现状 1.3 课题研究内容 1.4 相关知识概述 1..1 三层架构 “三层结构”一词中的“三层”是指：“表现层”、“中间业务层”、“数据访问层”。其中：表现层：位于最外层（最上层），离用户最近。用于显示数据和接收用户输入的数据，为用
