簡介：本科生畢業(yè)論文（設(shè)計）文獻(xiàn)綜述論文題目試卷分析評價系統(tǒng)學(xué)生姓名年級（學(xué)號）二級學(xué)院信息工程學(xué)院專業(yè)計算機科學(xué)與技術(shù)指導(dǎo)教師職稱填表日期2004年2月18日第三階段興起階段1994年以后。隨著改革開放的深入，國外大批軟件產(chǎn)品涌入中國，對民族軟件產(chǎn)業(yè)提出了嚴(yán)峻挑戰(zhàn)，同時也帶來了前所未有的機遇。一批飽經(jīng)磨礪的民族專業(yè)化軟件企業(yè)從激烈的競爭中得以生存發(fā)展，在教育、財務(wù)及商務(wù)管理、娛樂游戲等領(lǐng)域取得了一定的優(yōu)勢。這一階段的典型代表用友、金山、金蝶以及洪恩等。經(jīng)過二十年的發(fā)展，我國的軟件產(chǎn)業(yè)已經(jīng)初具規(guī)模，并展現(xiàn)了廣闊的前景。綜上所述，中國軟件產(chǎn)業(yè)已經(jīng)走過了一個從無到有、從弱到強、從單個企業(yè)到產(chǎn)業(yè)群落的發(fā)展歷程。值得我們驕傲和驚喜的是，中國軟件產(chǎn)業(yè)已經(jīng)保持了十年超過30的高速增長，更取得了舉國上下對其戰(zhàn)略地位的高度重視和一致認(rèn)知，越來越多的國人已經(jīng)開始認(rèn)識到軟件業(yè)是信息產(chǎn)業(yè)的真正核心和靈魂，如果我們這個泱泱大國沒有強大的軟件技術(shù)和軟件產(chǎn)業(yè)做后盾，也就無法真正凝聚中國信息產(chǎn)業(yè)的核心競爭力針對我所選的課題試卷分析評價系統(tǒng)，市面上已有相關(guān)類似的系統(tǒng)。如試卷處理設(shè)計。它采用VISUALFOXPRO50作為作為數(shù)據(jù)庫編程語言。此系統(tǒng)的試卷數(shù)據(jù)處理包括教師批閱試題、卷面計算、成績登記上報及各種試卷分析參數(shù)的計算。其中卷面計算、成績登記上報及各種試卷分析參數(shù)的計算等工作該系統(tǒng)能自動完成。工作模式為教師在試卷批閱完成后就轉(zhuǎn)入本系統(tǒng)，進(jìn)行數(shù)據(jù)輸入，其余工作由程序完成，實現(xiàn)試卷數(shù)據(jù)處理過程的高效、優(yōu)質(zhì)、規(guī)范。從整體上看該系統(tǒng)有考試信度分析、考試效度分析考、試成績分布的正態(tài)性檢驗、試題難度和區(qū)分度等。應(yīng)該說該系統(tǒng)是對我國教育工作現(xiàn)代化是一個比較創(chuàng)新的突破。但該系統(tǒng)卻是需要老師手動的批改試卷，因此還是有一點的不便。所以現(xiàn)在可以發(fā)展一種更高層次的系統(tǒng)，既可以對試卷進(jìn)行計算機批閱，也能自動對試卷進(jìn)行分析，以評價其質(zhì)量的好壞。要開發(fā)此種系統(tǒng)開發(fā)需要軟件編程語言與數(shù)據(jù)庫技術(shù)很好的結(jié)合。程序員使用各種編程語言編寫指令開發(fā)軟件，有些是計算機可以直接理解的，有些則需要中間翻譯的步驟。計算機語言大致可以分為三大類機器語言，匯編語言，高級語言。從編程人員來看高級語言要比機器語言和匯編語言都要強大的多。它使程序員能夠編寫更像自然語言的指令，可以包含常用的數(shù)字符號和表達(dá)式。而VISUALBASIC是功能非常強大、最廣泛使用的高級語言之一。VISUALBASIC是一個基于圖形用戶界面（GUI）的程序設(shè)計語言。友好的界面使得用戶更加容易學(xué)習(xí)、使用和樂于接受此類應(yīng)用。VISUALBASIC是從BASIC（BEGINNER’SALLPURPOSESYMBOLICINSTRUCTIONCODE）進(jìn)化而來的。BASIC是由DARTMOUTH學(xué)院的JOHNKEMENY和THOMASKURTZ教授在20世紀(jì)60年代中期作為編寫簡單程序的語言而開發(fā)的，BASIC的主要目的是幫助人們學(xué)會如何編程。BASIC在各種類型計算機（有時稱為硬件平臺）中的廣泛應(yīng)用使用使得這一語言的性能得以增強。隨著20世紀(jì)80年代后期和20世紀(jì)90年代初期MICROSOFTWINDOWS圖形用戶界面（GUI）的開發(fā)，BASIC自然進(jìn)化成VISUALBASIC，它是由MICROSOFT公司于1991年創(chuàng)建的。在VISUALBASIC出現(xiàn)以前，開發(fā)基于MICROSOFTWINDOWS的應(yīng)用程序是相當(dāng)困難和繁重的工作。VISUALBASIC極大地簡化了WINDOWS應(yīng)用程序的開發(fā)，自從1991年以來已經(jīng)發(fā)布了6個版本，最近的版本（VISUALBASIC6）出現(xiàn)在1998年。VISUALBASIC60中文版有如下優(yōu)點●完全中文化的環(huán)境使用戶更容易操作。在幾分鐘內(nèi)，就能熟悉VISUALBASIC60的開

簡介：1附件1外文資料翻譯譯文ASPNETASPNET概述概述ASPNET是一個統(tǒng)一的WEB開發(fā)模型，它包括您使用盡可能少的代碼生成企業(yè)級WEB應(yīng)用程序所必需的各種服務(wù)。ASPNET作為NETFRAMEWORK的一部分提供。當(dāng)您編寫ASPNET應(yīng)用程序的代碼時，可以訪問NETFRAMEWORK中的類。您可以使用與公共語言運行庫CLR兼容的任何語言來編寫應(yīng)用程序的代碼，這些語言包括MICROSOFTVISUALBASIC、C、JSCRIPTNET和J。使用這些語言，可以開發(fā)利用公共語言運行庫、類型安全、繼承等方面的優(yōu)點的ASPNET應(yīng)用程序。ASPNET包括?頁和控件框架?ASPNET編譯器?安全基礎(chǔ)結(jié)構(gòu)?狀態(tài)管理功能?應(yīng)用程序配置?運行狀況監(jiān)視和性能功能?調(diào)試支持?XMLWEBSERVICES框架?可擴展的宿主環(huán)境和應(yīng)用程序生命周期管理?可擴展的設(shè)計器環(huán)境ASPNET頁和控件框架是一種編程框架，它在WEB服務(wù)器上運行，可以動態(tài)地生成和呈現(xiàn)ASPNET網(wǎng)頁?？梢詮娜魏螢g覽器或客戶端設(shè)備請求ASPNET網(wǎng)頁，ASPNET會向請求瀏覽器呈現(xiàn)標(biāo)記（例如HTML）。通常，您可以對多個瀏覽器使用相同的頁，因為ASPNET會為發(fā)出請求的瀏覽器呈現(xiàn)適當(dāng)?shù)臉?biāo)記。但是，您可以針對諸如MICROSOFTINTERNETEXPLORER6的特定瀏覽器設(shè)計3庫使用ASPNETFORMS身份驗證和ASPNET成員資格來管理身份驗證。此外，可以使用WINDOWS組或您自己的自定義角色數(shù)據(jù)庫（使用ASPNET角色）來管理WEB應(yīng)用程序的功能和信息方面的授權(quán)。您可以根據(jù)應(yīng)用程序的需要方便地移除、添加或替換這些方案。ASPNET始終使用特定的WINDOWS標(biāo)識運行，因此，您可以通過使用WINDOWS功能（例如NTFS訪問控制列表ACL、數(shù)據(jù)庫權(quán)限等等）來保護(hù)應(yīng)用程序的安全。ASPNET提供了內(nèi)部狀態(tài)管理功能，它使您能夠存儲頁請求期間的信息，例如客戶信息或購物車的內(nèi)容。您可以保存和管理應(yīng)用程序特定、會話特定、頁特定、用戶特定和開發(fā)人員定義的信息。此信息可以獨立于頁上的任何控件。ASPNET提供了分布式狀態(tài)功能，使您能夠管理一臺計算機或數(shù)臺計算機上同一應(yīng)用程序的多個實例的狀態(tài)信息。通過ASPNET應(yīng)用程序使用的配置系統(tǒng)，可以定義WEB服務(wù)器、網(wǎng)站或單個應(yīng)用程序的配置設(shè)置。您可以在部署ASPNET應(yīng)用程序時定義配置設(shè)置，并且可以隨時添加或修訂配置設(shè)置，且對運行的WEB應(yīng)用程序和服務(wù)器具有最小的影響。ASPNET配置設(shè)置存儲在基于XML的文件中。由于這些XML文件是ASCII文本文件，因此對WEB應(yīng)用程序進(jìn)行配置更改比較簡單。您可以擴展配置方案，使其符合自己的要求。ASPNET包括可監(jiān)視ASPNET應(yīng)用程序的運行狀況和性能的功能。使用ASPNET運行狀況監(jiān)視可以報告關(guān)鍵事件，這些關(guān)鍵事件提供有關(guān)應(yīng)用程序的運行狀況和錯誤情況的信息。這些事件顯示診斷和監(jiān)視特征的組合，并在記錄哪些事件以及如何記錄事件等方面提供了高度的靈活性。ASPNET支持兩組可供應(yīng)用程序訪問的性能計數(shù)器?ASPNET系統(tǒng)性能計數(shù)器組?ASPNET應(yīng)用程序性能計數(shù)器組
