文件共享管理系统的设计与实现

摘要：本文件共享管理系统解决了用户在搜索文件不需要下载文件到本地硬盘后才能查看文件的详细内容的弊端；解决用户在搜索关键字不明确条件下无法搜索到自己需要的文件弊端；解决了系统用户并发量增加后服务器宕机而无法提供服务的弊端；解决服务器面对大量业务处理数据读取速度过慢的弊端；解决用户登录密码在 http 协议下被轻易窃取的弊端。

本文件共享管理系统，通过构建服务器集群和分布式数据库集群来满足互联网用户的并发访问，提高用户请求的响应时间；系统依赖于缓存服务器提高对数据的访问速度；通过对用户上传文件的处理使得文件可以被用户在线浏览；保证用户文件的安全性采用单独的服务器进行存储；通过使用全文检索框架对用户输入关键字智能分析。

本系统采用恰当的技术来解决上述问题从而为用户提供良好的操作体验。

The Design and Implementation of File Sharing Management System

Abstract：This file sharing management system to solve the user in the search for files do not need to download the file to the local hard disk to check the file details of defects;To solve the user in the search keywords don't conditions to search the drawbacks of the file to your questions;Solved the system user concurrency value increased after the server goes down to the disadvantages of service;Solve the server  in the face of the disadvantages of a large number of business processing data read speed too slow;To solve the user login password under the HTTP protocol is easy to steal.

This file sharing management system, this paper builds and distributed database cluster server cluster to meet concurrent access to Internet users, to improve the response time of user request;System is dependent on the cache server to increase the speed of access to data;Based on the user to make the file upload files can be read by users online;To ensure the safety of the user files using a separate server to store;Through the use of full text retrieval framework for user input keyword intelligence analysis.

This system USES the appropriate technology to solve the above problems so as to provide good experience for the user.
