在线选课系统论文

兰州交通大学毕业设计(论文)I摘要随着办公自动化技术的发展，利用计算机对信息进行自动化处理已经被各个群体广泛应用。为了提高学生选课的效率，借助计算机和网络技术来帮助学生选课是非常有必要的。以往的选课方式都是随堂报名的，而通过互联网在线选课比传统的选课方式更加方便，在提高选课效率的同时增加了学生选课的兴趣。因此，很有必要开发在线选课系统。首先，本系统根据大部分院校选课的需求，采用B/S(浏览器/服务器)模式的基本设计思想对整个系统进行设计，然后把系统划分为系统管理员、教师、学生三部分分别进行设计与编码实现。基本实现了管理员对学生的选修课程进行管理、学生在线选课、老师提交学生成绩等功能。在线选课系统运用了Java、JSP、MySQL等技术完成了数据库的设计与开发、系统详细设计。关键词：在线选课系统，B/S，数据库设计兰州交通大学毕业设计(论文)IIAbstractWiththedevelopmentofofficeautomationtechnology,usingacomputertodealwiththeinformationautomaticallyhavebeenwidelyused.Toimproveefficiencyofstudents'choosingclasses,usingcomputersandnetworktechniquetohelpstudentschooseclassesisnecessary.Previouswaysofchoosingcoursesareclassregistration,buttheonlinecourseselectionviatheInternetismoreconvenientthanthetraditionalwaysofchoosingacourse,anditalsoincreasesstudents'interestsofchoosingcourses.Thus,itisnecessarytodeveloptheonlinecourseselectionsystem.Atfirst,accordingtotherequirementsofmostofthecollege,thissystemdesignsoverallsystemusingB/Spattern,andsystemisdividedintoadministrator,teachersandstudentsthreeparts,respectivelyfordesignandcodeimplementation.Ithasbasicallyachievedadministratormanagingstudents'electivecourses,studentsonlinecourseselection,theteacherssubmittingstudentachievementandsoon.OnlinecourseselectionsystemusesJava,JSP,MySQLandothertechniquestoachievethedesignanddevelopmentofdatabaseandsystemdetaileddesign.Keywords:TheOnlineCourseSelectionSystem,B/Smode,databasedesign兰州交通大学毕业设计(论文)III目录摘要.............................................................................................................................................IAbstract......................................................................................................................................II1.绪论.....................................................................................................................................11.1课题背景.....................................................................................................................11.2开发的目的和意义.....................................................................................................11.3系统设计路线.............................................................................................................21.4论文组织结构.............................................................................................................22.系统关键技术介绍.............................................................................................................32.1JavaEE架构................................................................................................................32.2MVC架构....................................................................................................................32.3JSP技术.......................................................................................................................42.4Tomcat服务器.............................................................................................................42.5MySQL数据库............................................................................................................42.6基于B/S模式的三层架构.........................................................................................52.7系统开发环境.............................................................................................................52.8开发方法.....................................................................................................................63.可行性分析.........................................................................................................................73.1系统流程图.................................................................................................................73.1.1管理员流程图..................................................................................................73.1.2学生流程图......................................................................................................73.1.3教师流程图......................................................................................................83.2用户需求.....................................................................................................................83.3系统需求.....................................................................................................................93.4功能需求.....................................................................................................................93.4.1前端界面需求..................................................................................................93.4.2后端管理需求................................................................................................103.5可行性分析...............................................................................................................103.5.1经济可行性分析............................................................................................113.5.2技术可行性....................................................................................................11兰州交通大学毕业设计(论文)IV3.5.3运行可行性......................
