【正文】 s. In systems analysis the system structure was used to analyze the mail system, including the functional processes and functional analysis, database tables. During the entire system design , the various user system functional modules, menu design were detailed displayed .Meanwhile in the system realization , the corresponding backstage database service , the onstage function event controller and the code as well as the contact surface realization method were offered in the realization table list . Finally, the corresponding test has been given to system design each function, and the correlation design page section directviewing chart has been produced.Key words: C。 SQL Server. . . . .學習參考目 錄論文總頁數(shù)：28 頁1 引言 ............................................................................................................................................1 郵件系統(tǒng)的介紹 ................................................................................................................1 開發(fā)概述 ............................................................................................................................1 對電子郵件的現(xiàn)狀分析 ....................................................................................................2 電子郵件的發(fā)展前景 ........................................................................................................22 開發(fā)分析 ....................................................................................................................................3 開發(fā)背景 ............................................................................................................................3 工作原理分析 ....................................................................................................................33 系統(tǒng)設計 ....................................................................................................................................4 模塊的劃分與功能設計 ....................................................................................................4 功能模塊的初步設計 ........................................................................................................5 前臺分析 ............................................................6 后臺分析 .............................................................6 數(shù)據(jù)庫設計 ........................................................................................................................7 模塊的組織結構 ................................................................................................................94 系統(tǒng)詳細設計 ..........................................................................................................................11 用戶“注冊” 的設計 ..........................................................................................................11 用戶“登路” 的設計 ..........................................................................................................12 修改用戶密碼的設計 ......................................................................................................13 新建文件夾 ......................................................................................................................14 閱讀郵件 ..........................................................................................................................15 重命名文件夾 ..................................................................................................................16 發(fā)送郵件 ..........................................................................................................................17 郵件用戶管理 ..................................................................................................................205 系統(tǒng)功能界 面演示 ..................................................................................................................21 用戶注冊功能界面演示 ..................................................................................................21 管理功能界面演示 ..........................................................................................................23 接收送功能界面演示 ......................................................................................................24結 論 ..........................................................................................................................................25參考文獻 ..........................................................................................................................................25. . . . .學習參考1 引言 郵件系統(tǒng)的介紹伴隨著信息技術的快速發(fā)展，電子郵件已經(jīng)成為最基本的網(wǎng)絡通信工具，每天都有成千上萬的用戶使用它。這種非交互式的通信,加速了信息的交流及數(shù)據(jù)傳送,它是—個簡易、快速的方法。利用電子
