在线作业提交与批改系统设计与开发

摘要随着教育改革的提出，网络教育成为了教育改革的新方向，并已成为现代教育的一个突出特征，推动着教育的发展。课后作业是教育中不可缺少的一部分，传统的模式如果时间久了，管理十分不便利，一旦数据过多，就十分混乱，如何有效管理这些作业就成为一个重要的课题。而本毕业设计就是为了解决这些问题，主要任务就是采用计算机系统来管理在线作业提交与批改信息，达到减少人力物力财力、节省管理的时间、提升工作效率的目的。本系统主要分为前台与后台两部分。前台为师生服务，其主要功能有：个人信息管理、课程信息管理、作业提交及批改等：后台为管理员服务，其功能有：用户管理、公告管理、课程管理等。通过这些功能模块设计，基本上涵盖了整个在线作业提交与批改系统的过程。本文将结合在线作业提交与批改系统的开发过程，先对系统的功能需求和性能需求进行具体分析，再详细地介绍系统的结构设计、数据库设计以及程序的编码工作，最后对系统的各个功能模块进行测试和优化。目前系统全部功能都已经通过测试，可以稳定运行。关键词：作业系统：课程管理；网页开发：Spring BootAbstractWith the proposal of education reform,online education has become a new direction foreducation reform and a prominent feature of modern education,driving the development ofeducation.Homework is an indispensable part of education,but the traditional mode becomesvery inconvenient to manage over time and can become chaotic with too much data.Effectivemanagement of these assignments has become an important issue.This graduation project aimsto solve these problems by using a computer system to manage online homework submission andgrading information,reducing manpower,material resources,and financial resources,savingmanagement time,and improving work efficiency.The system consists of front-end and back-end.The front-end serves teachers and students,with functions including managing personal information,course information,homeworksubmission and grading;the back-end is mainly used by administrators,with functions includinguser management,announcement management,and course management.By designing thesefunctional modules,the whole process of submitting and grading on line is basically covered.This article will combine the development process of the online homework submission andgrading system to analyze the specific functional requirements and performance requirements ofthe system,and then introduce the structure design,database design,and coding work of thesystem in detail.Finally,each functional module of the system will be tested and optimized.Currently,all functions of the system have passed testing and can run stably.Key words:Homework system;course management;web development;Spring Boot目录目录摘.44444444AbstractⅢ第1章绪论.1.1在线作业提交与批改系统开发的相关背景.......41.2课题研究目的和意义.41.3国内外研究现状...41.4课题研究的主要内容..61.5论文组织结构61.6本章小结.6第2章关键技术分析.72.1初步调查...72.2B/S架构....72.3Java技术介绍.72.4 MySQL数据库介绍….82.5 Spring Boot框架.82.6本章小结...9第3章系统需求分析103.1系统业务需求分析..103.2系统功能需求分析..103.3系统非功能需求分析.103.4系统经济性分析113.5系统社会影响分析..113.6本章小结..12第4章系统设计....…。。。。。134.1系统总体设计概述134.2系统总体结构设计..134.3系统功能模块设计...144.3.1登录模块设计.144.3.2个人中心模块设计144.3.3公告管理模块设计.154.3.4用户管理模块设计..154.3.5课程管理模块设计154.3.6作业管理模块设计…164.4数据库设计....16
