1摘要本論文主要闡述了基于Web技術的英語網絡考試系統(tǒng)的設計與實現(xiàn)。在介紹動態(tài)網頁程序開發(fā)和數據訪問技術基礎上，提出了網絡英語考試系統(tǒng)的組成與結構，闡述了系統(tǒng)的設計方案、實現(xiàn)方法以及所采用的開發(fā)工具和相關技術，還重點剖析了前臺考試部分的程序設計。本考試系統(tǒng)采用B/S模式開發(fā)，不需安裝客戶端，被授權用戶通過瀏覽器即可登錄系統(tǒng)，從而開始正常的考試。本系統(tǒng)是基于微軟公司的Windows2000操作系統(tǒng)、Internet信息管理器與SQLServer數據庫平臺構建而成。微軟公司產品優(yōu)異的性能為本系統(tǒng)提供了高效穩(wěn)定的運行環(huán)境，使本系統(tǒng)無論在運行速度、易用性還是在數據吞吐能力方面都表現(xiàn)卓越。本系統(tǒng)采用了以下技術方案保證考試正常穩(wěn)定的進行。全面的容錯處理使考試作業(yè)流程得到有序的控制，對用戶的誤操作能夠進行有效的屏蔽；在考試過程中，禁止考生刷新瀏覽器，防止考生誤操作導致答案丟失；對鼠標右鍵操作進行限制，保證考試系統(tǒng)用戶界面的完整性；另外，系統(tǒng)還提供了考試時間倒計時功能，使考生隨時了解考試剩余時間。在考試結束前一分鐘和最后10秒種，系統(tǒng)會提醒考生注意保存答案，防止答案丟失。考試到時后，如果考生還未提交試卷，系統(tǒng)將自動交卷，保證考試嚴肅、公正的進行。關鍵字：網絡考試系統(tǒng)英語考試WebASP2AbstractThepresentpapermainlyelaboratedbasedontheWebtechnologyEnglishnetworktestsystemdesignandtherealization.Intheintroductiondynamichomepageproceduredevelopmentandinthedataaccessingtechnologybase,proposedthenetworkEnglishtestsystemcompositionandthestructure,elaboratedthesystemdesignproposal,therealizationmethodaswellasusedevelopmentkitandcorrelationtechnology,butalsoanalyzedthepartiallinksprogrammingwithemphasis.HaveanexaminationsystemadoptB/Smodedevelopment,needtoinstallthecustomerendoriginally,authorizeduserstologintothesystemthroughthebrowser,thusbeginthenormalexamination.ThissystemwasstructuredwithSQLServerdatabaseplatformbyaWindows2000operatingsystembasedonMicrosoft,Internetinformationmanagementdevice.TheperformancethattheproductsofMicrosoftareexcellenthasofferedthehigh-efficientandsteadyrunningenvironmentforthissystem；makethissystemnomatteratthespeed,apttobehavewiththesexorinhandlingcapacityofthedataremarkablyofoperation.Thissystemadoptagreatdealoftechnologicalschemeisithaveanexaminationnormalgoingonsteadytoguarantee.Overallfault-toleranttreatmentmakeshavinganexaminationandgetsorderlycontrolinprocedureofthehomework,cancarryontheeffectiveshieldingtousersmistakeoperation；Inthecourseofexamination,forbidexamineestobreakthebrowser,preventtheexaminee3fromoperatingandcausingtheanswertolosebymistake；Isitisitlimittogoontooperatebyrightkeytomouse,isithaveanexaminationsystematicuserintegralityofinterfacetoguarantee；Inadditionsystemoffertesttimecount-downfunction,makeexamineeisithaveanexaminationsurplustimetounderstandatanytime.Inexaminationoneminuteandlastonesecondkindbeforefinishing,systemwillremindexamineepayattentiontoanswerofkeeping,preventtheanswerfrombeinglost.Examinationthen,ifexamineesubmitpaperyet,systemhandinanexaminationpaperautomatically,guaranteeitisserioustohaveanexamination,justgoingon.KeyWords:NetworkExamSystem,EnglishExam,Web,andAsp4目錄1引言.12緒論.22.1網絡考試系統(tǒng)與B/S結構.22.2數據庫.22.3數據庫訪問技術.32.4開發(fā)平臺與開發(fā)工具.42.4.1系統(tǒng)軟件.42.4.2工
