70网上选课系统的设计与实现

网上选课系统的设计与实现-I-摘要随着计算机技术的飞速发展，高校也已进入信息化时代。为了使高校管理更高校、更科学，决定开发网上选课系统。本文采用结构化分析的方法，首先进行系统开发背景的介绍，系统的开发目的；接下来系统的关键技术以及系统开发模式的介绍；之后是系统分析，包括系统可行性分析，业务流程分析，数据流程分析和数据字典；然后是系统设计，包括功能设计和数据库的设计；接下来是系统实现，主要讲述了系统的界面实现；最后是系统测试，测试了本系统的功能和性能。本系统用ASP+SQL2000开发，开发过程中运用了页面模块化、信息发布的动态生成、静态页面显示等技术开发。系统开发模式采用B/S模式。本系统的设计实施为网上选课系统的运行做基础，为网上选课管理工作提供良好的条件。关键词：网上选课；结构化分析；系统网上选课系统的设计与实现-II-AbstractWiththerapiddevelopmentofcomputertechnology,theuniversitieshaveenteredtheinformationage.Tomakeuniversitymanagementmoreuniversities,morescientific,decidedtodeveloptheonlinecourseselectionsystem.Inthispaper,themethodofstructuredanalysis,thefirstintroductionofthesystemdevelopmentbackground,thepurposeofsystemdevelopment;theintroductionofthenextkeytechnologyofthesystemandsystemdevelopmentmodel;aftersystemanalysis,includingthesystemfeasibilityanalysis,businessprocessanalysis,dataprocessanalysisanddatadictionary;andsystemdesign,includingfunctionaldesignanddatabasedesign;next,thesystemfocusesontheinterfaceofthesystem;Finally,systemtesting,testthefunctionalityandperformanceofthesystem.ThesystemASP+SQL2000development,thedevelopmentprocessusingthepagemodular,dynamicallygeneratedinformation,staticpagesdisplaytechnologydevelopment.SystemdevelopmentmodelwithB/Smode.Thedesignandimplementationofthissystemasafoundationfortheoperationoftheonlinecourseselectionsystem,providegoodconditionsforOnlineCoursemanagement.Keywords:OnlineCourse;structuredanalysis;system网上选课系统的设计与实现-III-目录摘要.............................................................................................................................IAbstract..............................................................................................................................II第1章引言......................................................................................................................11.1系统开发背景.....................................................................................................11.2系统开发意义.....................................................................................................21.3管理系统概述.....................................................................................................21.3.1管理信息系统概念及其发展..........................................................................21.3.2管理信息系统的功能......................................................................................21.3.3管理信息系统的开发方法..............................................................................3第2章关键技术介绍......................................................................................................52.1网页设计工具的选择.........................................................................................52.2编程语言的选取.................................................................................................82.3数据库的选取...................................................................................................102.4系统开发模式...................................................................................................12第3章系统分析............................................................................................................153.1系统可行性分析...............................................................................................153.1.1技术可行性....................................................................................................153.1.2经济可行性....................................................................................................153.1.3社会可行性....................................................................................................153.2业务流程分析...................................................................................................163.3数据流图...........................................................................................................183.4数据字典...........................................................................................................20第4章系统设计............................................................................................................234.1系统功能设计...................................................................................................234.2系统数据库设计...............................................................................................244.2.1概念结构设计................................................................................................25网上选课系统的设计与实现-IV-4.2.2数据库表设计................................................................................................29第5章系统实现............................................................................................................335.1登录模块............................................................................................................335.2修改密码界面...................................................................................................355.3学生管理界面...................................................................................................355.4成绩管理界面.................................................................
