JSP3006SMART系統(tǒng)-考試監(jiān)控及閱卷模塊的設(shè)計(jì)與開發(fā)2

1、SMART系統(tǒng)考試監(jiān)控及閱卷模塊的設(shè)計(jì)與開發(fā)摘 要Smart在線考試評(píng)估系統(tǒng)(簡(jiǎn)稱“SMART系統(tǒng)”)，是基于Browser/Server（簡(jiǎn)稱B/S）結(jié)構(gòu)的數(shù)據(jù)庫訪問模式，采用Struts + Spring + Hibernate作為平臺(tái)搭建的框架開發(fā)的一套新型智能的遠(yuǎn)程教育軟件。主要用于各中小學(xué)的學(xué)生考試和教學(xué)評(píng)估。本論文設(shè)計(jì)作為Smart項(xiàng)目的一個(gè)組成部分，主要實(shí)現(xiàn)了考試過程監(jiān)控和客觀題的自動(dòng)閱卷功能。論文首先介紹了設(shè)計(jì)中所涉及到的項(xiàng)目背景、開發(fā)技術(shù)，并構(gòu)建了系統(tǒng)的總體框架；其次根據(jù)中小學(xué)的實(shí)際情況和遠(yuǎn)程教育軟件項(xiàng)目的需求，詳細(xì)地進(jìn)行了數(shù)據(jù)庫設(shè)計(jì)和系統(tǒng)功能模塊設(shè)計(jì)，制定了各功能模塊的流程

2、圖；然后采用JAVA編程語言對(duì)本論文的設(shè)計(jì)任務(wù)進(jìn)行編碼，并最終實(shí)現(xiàn)了對(duì)考試過程的監(jiān)控和對(duì)客觀題的自動(dòng)閱卷等功能。通過本模塊的應(yīng)用，可以滿足SMART系統(tǒng)的在線考試部分需求，對(duì)SMART系統(tǒng)的應(yīng)用和發(fā)展起到一定的促進(jìn)作用。關(guān)鍵詞：Hibernate；在線考試；考試監(jiān)控；閱卷The SMART SystemDesign and Implementation The Module of The Examination Controls and Paper InspectionAbstractSmart online examination and evaluation system, as SMAR
