网络选课系统的设计与实现毕业设计（论文）题目院系控制与计算机工程学院专业班级xxxx班学生姓名Xxx指导教师Xxx二○○年六月网络选课系统的设计与实现I摘要一个网络选课系统所应包括的基本功能包括对教师、学生、课程等基本信息，学生选课以及教师操作的管理。本系统对学生提供个人信息维护，选课以及查看所选课程的信息和成绩等功能；对教师提供个人信息维护，增删选课的学生，登记学生的成绩等功能；管理员可以对所有的学生、教师、课程、院系、班级的基本信息进行添加、删除和修改，并能够修改密码，对选课进行确认，控制学生和教师操作的权限等。本系统以MyEclipse为开发工具，SQLServer2012为数据库软件，采用基于Web的JSP+JavaBean+Servlet技术和B/S结构。利用JSP，HTML进行网站总体风格、界面的设计与开发，利用JavaBean和Servlet进行实际的程序开发，对后台数据库进行操作。Servlet主要用于获取从网页传来的操作命令，调用JavaBean的函数，最后跳转到相应的网页页面。JavaBean主要用于检查操作的可执行性和执行SQL语句。本系统参照了本校的选课系统的一些特点，实现了与选课相关的一些基本功能。关键词：网络选课系统，JSP+JavaBean+Servlet，B/S，SQLServer2012IIABSTRACTBasicfunctionsofanonlinecourse-selectingsystemshouldincludethemanagementofthebasicinformationofteachers,students,curriculumsandstudentenrollmentandteacheroperations.Thissystemprovidesthestudentthefunctionsofpersonalinformationmaintenance,courseselection,viewingtheselectedcurriculumsandscores,etc;andprovidesteachersthefunctionsofpersonalinformationmaintenance,additionsanddeletionsofelectivestudents,registeringscoresofstudents,etc;administratorscanadd,deleteandmodifybasicinformationofallstudents,teachers,curriculums,facultiesandclasses,andcanchangethepassword,comformthecourseselection,controltheauthorityoftheoperationsofstudentsandteachers,etc.ThissystemusesMyEclipseasthedevelopingtool,SQLServer2012asthedatabasesoftware,andusesaWeb-basedJSP+JavaBean+ServlettechnologyandB/Sstructure.ItusesJSP,HTMLforthedesigninganddevelopmentofwebsites’overallstyleandinterface,JavaBeanfortheactualprogramdevelopmentandoperatingonthebackgrounddatabase.ServletismainlyusedtogetcommandscomingfromwebpagesandcallthefunctionsofJavaBeanandfinallyjumptothecorrespondingwebpages.JavaBeanismainlyusedtochecktheexecutabilityofoperationsandexecuteSQLstatements.Thesystemreferstosomecharacteristicsofourschool’scourse-selectingsystemandachieveswithsomeofthebasicfunctionsrelatedtocourseselection.Keywords:onlinecourse-selectingsystem,JSP+JavaBean+Servlet,B/S,SQLServer2012华北电力大学本科毕业设计（论文）目录摘要......................................................................................................................................IABSTRACT.................................................................................................................................II第1章绪论...................................................................................................................................11.1背景和意义...........................................................................................................................11.2国内外研究现状...................................................................................................................11.3研究内容及预期目标...........................................................................................................1第2章相关理论及技术分析.......................................................................................................32.1运行环境及系统结构...........................................................................................................32.2B/S模式结构.........................................................................................................................32.3系统采用的关键技术...........................................................................................................42.3.1JSP...................................................................................................................................42.3.2JavaBean..........................................................................................................................52.3.3Servlet..............................................................................................................................52.4J2EE技术架构......................................................................................................................6第3章可行性研究与需求分析...................................................................................................73.1系统体系结构.......................................................................................................................73.2系统开发过程.......................................................................................................................73.3可行性研究...........................................................................................................................73.4需求分析...............................................................................................................................83.4.1系统设计目标和基本功能.............................................................................................83.4.2用户登录功能................................................................................................................83.4.3管理员功能....................................................................................................................83.4.4学生功能........................................................................................................................83.4.5教师功能........................................................................................
