【正文】 基于 JAVA的郵件收發(fā)系統(tǒng)的設(shè)計摘 要在經(jīng)濟全球化和信息技術(shù)飛速發(fā)展的今天，通過郵件收發(fā)進(jìn)行信息傳遞已經(jīng)成為主流。目前，基于 B/S（Browser/Server）模式的 MIS（Management information system）日益成熟，Web 已從靜態(tài)的 HTML 到動態(tài)的網(wǎng)頁，使系統(tǒng)的開發(fā)、管理和維護(hù)變得非常方便。因此，本系統(tǒng)研究并開發(fā)了基于 B/S 模式的郵件收發(fā)程序系統(tǒng)?！多]件收發(fā)程序的設(shè)計與開發(fā)》是一個綜合性的程序設(shè)計，涉及到界面、系統(tǒng)、數(shù)據(jù)庫、協(xié)議、編碼等多個方面的內(nèi)容。 技術(shù),后臺數(shù)據(jù)庫采用 SQL Server 2022，語言采用 C，主要講述了郵件系統(tǒng)的注冊、登陸、管理、發(fā)送和接收郵件等基本功能及設(shè)計方法。在系統(tǒng)分析中先后用系統(tǒng)的結(jié)構(gòu)圖分析了郵件系統(tǒng)，包括功能流程和功能分析，數(shù)據(jù)庫表格。在整個系統(tǒng)的設(shè)計中，詳細(xì)的展現(xiàn)了用戶系統(tǒng)的各個功能模塊，菜單的設(shè)計等。同時在系統(tǒng)的實現(xiàn)中，給出了實現(xiàn)表單中相應(yīng)的后臺數(shù)據(jù)庫服務(wù)，前臺功能控件的事件及代碼以及界面實現(xiàn)的方法。最后，對系統(tǒng)設(shè)計的各個功能做了相應(yīng)測試，并給出了相關(guān)設(shè)計頁面截面的直觀圖。關(guān)鍵字：C；郵件系統(tǒng)；SQL Server數(shù)據(jù)庫The Designing and Development of Email Receiving and Sending SystemAbstractRecently as the economic became globalization and the information technology developed rapidly, the level of enterprise Information is the key to drive the technological innovation and to upgrade of all work. Currently, the model of MIS (Management Information System) based on the B/S (Browser/Server) is being increasingly mature and enterprise Web have already been from static HTML to dynamic website, which allowing the system to the development, management and maintenance became convenience. Therefore, this system researched and developed the inventory management information system based on the B/S mode.《The designing and development of Email receiving and sending system》is a prehensive design process involving the interface, system, database, agreement, coding and other aspects .The designing uses .NET technology, background database using SQL Server 2022, C as language. It mainly described the mail system on the registration, landing, and management, sending and receiving mail and other basic functions and design methods. 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。 Email System。 SQL Server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(shè)計 ....................................................................................................................................4 模塊的劃分與功能設(shè)計 ....................................................................................................4 功能模塊的初步設(shè)計 ........................................................................................................5 前臺分析 ............................................................6 后臺分析 .............................................................6 數(shù)據(jù)庫設(shè)計 ........................................................................................................................7 模塊的組織結(jié)構(gòu) ................................................................................................................94 系統(tǒng)詳細(xì)設(shè)計 ....................................................
