1、绪论
1.1 项目背景
随着计算机行业的发展,知识的获取手段不仅局限于纸质笔记,越来越多的学生也喜欢在计算机平台上进行学习,继而衍生出各式各样的学习网站和系统。该类产品的诞生也推动了整个学习模式从传统线下转向信息化,给学生提供学习经验分享的新型沟通平台,打破无形的信息屏障。现如今社会处于紧急疫情防控状态,为了避免出现有接触学习方式,为了方便用户学习,就是在互联网时代,借助计算机手段设计一个基于SSM+Vue的在线课堂学习做题系统,达到方便、灵活、高效、实用的效果,符合当今智能化和现代化管理模式。
1.2 项目意义
本系统主要根据用户和管理员的需求做出分析,让用户更好的在线查看课程视频、在线做题、在线答疑等,管理人员更好的管理信息,还可以给用户提供课程资料的学习,在线交流问答等功能。管理员对信息进行管理等。从这个系统的操作来说:它能够有效的进行信息的添加、修改、查询、删除一些信息并进行管理,在一定的程序上能够实现了自动化。设计该系统的主要目的是为实现通过网络来减少人力和财力的投入,不断提高工作效率。 最终我们希望通过在线课堂设计与实现可以达到以下目的: 1、提高在在线课堂学习做题系统设计与实现信息管理的效率,实现管理上的井井有条。 2、实现用户通过计算机平台及时进行更新网站信息,查看信息等。 3、解决在线课堂学习做题系统设计与实现,存在的弊端。 计算机技术在现代管理中的应用,使计算机成为用户应用现代技术的重要工具。能够有效的解决获取信息便捷化、全面化的问题,提高效率。
2、核心功能模块
2.1 系统功能模块分析
基于SSM+Vue的在线课堂学习做题系统采用B/S的结构,Java语言进行设计,后台上采用Mysql数据库。 在线课堂学习做题系统的主要使用者分为管理员和用户,实现功能包括: ①管理员功能:首页、个人中心、用户管理、课程分类管理、在线学习管理、试卷管理、试题管理、系统论坛、系统管理、考试管理。
②用户功能:首页、在线学习、系统论坛、试卷列表、系统公告、个人中心、在线答疑,我的收藏管理、线上做题等操作。
