C语言教学网站及网上考试系统的设计与实现ASP.NET+SQL Sever2000论文.doc

毕业设计论文说明书题目C语言教学网站及网上考试系统的设计与实现毕业设计(论文)中文摘要C语言教学网站及网上考试系统的设计与实现摘要本文叙述了教学方式及考试方式的历史、现状、以及ASP.NET语言和SQLserver2000数据库管理系统的概况。重点介绍了C语言教学网站、网上考试系统和在线交流模块的实现过程包括系统分析、系统调查、数据流程分析、功能设计、数据库设计、系统的运行环境、系统测试及调试。本系统主要面向两类人员使用管理员(教师)、普通学生,他们拥有不同的权限。考试模块使用的过程是管理员添加试题,制订出题规则,生成试卷。学生登录后选择要考的试卷然后进入答题,完毕后提交试卷,存入数据库并评分。系统管理员可以查询考生的成绩,每个考生只能查询自己的成绩。教学网站模块,管理员添加教学文档,并对文档进行分类、修改等操作,而普通用户只能浏览内容。在线交流模块中,任何用户都可以登录留言,管理员可以删除留言。另外总结了本系统的特点节约教学成本,提高考试工作的效率。关键词ASP.NETSQLserver2000B/SC语言教学网站考试系统毕业设计(论文)外文摘要DesignandimplementationontheteachingwebofClanguageandexaminationsystembasedonwebAbstractThisthesisnarratedtheteachingwayandthetestwayhistory,thepresentsituation,aswellasASP.NETlanguageandtheSQLSEVER2000databasemanagementsystemsurvey.IntroducedwithemphasisontheClanguageteachingwebsite,thenettakesatestsystematicandtheonlineexchangemodulerealizationprocessIncludingsystemanalysis,systeminvestigation,dataflowanalysis,functionaldesign,databasedesign,systemmovementenvironment,systemtestanddebugging.ThissystemmainlyfacestwokindofpersonneltouseThemanager,theordinarystudent,theyhavethedifferentjurisdiction.Thetestmoduleuseprocessisthemanagerincreasesthetestquestion,themakingsetsthetopicofacompositiontherule,theproductionexaminationpaper.Thestudentregisterstheexaminationpaperwhichthepostselectionneedstotestthentoentertheanswer,afterfinishedsubmitstheexaminationpaper,storesthedatabaseandgrades.Thesystemmanagermayinquireexamineesresult,eachexamineeonlycaninquireownresult.Theteachingwebsitemodule,themanagerincreasestheteachingdocuments,andcarriesonoperationsandsoonclassification,revisiontothedocuments,buttheaverageconsumeronlycanglanceoverthecontent.Intheonlineexchangemodule,anyusersallmayregisterthemessage,themanagermaydeletethemessage.MoreoversummarizedthissystemcharacteristicSavestheteachingcost,enhancesthetestworktheefficiency.KeywordsASP.NETSQLserverB/SteachingwebofClanguageExaminesystem目录1.引言.................................................................................................................................................................11.1课题研究背景与意义.........................................................................................................................11.1.1网上教学系统..........................................................................................................................11.1.2网上考试系统..........................................................................................................................11.2问题定义内容简介..............................................................................................................................11.2.1问题定义..................................................................................................................................11.2.2内容简介..................................................................................................................................21.3课题调研与可行性分析......................................................................................................................21.3.1课题调研...................................................................................................................................21.3.2可行性分析..............................................................................................................................21.4论文各章内容介绍..............................................................................................................................32.系统的需求分析.............................................................................................................................................42.1系统功能需求.......................................................................................................................................42.2业务流和数据流图..............................................................................................................................42.2.1业务流.......................................................................................................................................42.2.2数据流图...................................................................................................................................52.3数据字典..............................................................................................................................................62.3.1数据流分量..............................................................................................................................62.3.2数据流......................................................................................................................................82.3.3数据存储..................................................................................................................................82.3.4数据处理..................................................................................................................................83.系统设计...................................................................................................................................................
