SprinBoot+Vue远程教育网站的设计与实现(源码+数据库+文档)

项目描述
信息数据从传统到当代，是一直在变革当中，突如其来的互联网让传统的信息管理看到了革命性的曙光，因为传统信息管理从时效性，还是安全性，还是可操作性等各个方面来讲，遇到了互联网时代才发现能补上自古以来的短板，有效的提升管理的效率和业务水平。传统的管理模式，时间越久管理的内容越多，也需要更多的人来对数据进行整理，并且数据的汇总查询方面效率也是极其的低下，并且数据安全方面永远不会保证安全性能。结合数据内容管理的种种缺点，在互联网时代都可以得到有效的补充。
本论文在结合先进的互联网技术下，开发出了符合需求的软件，让数据内容管理不管是从录入的及时性，查看的及时性还是汇总分析的及时性，都能让正确率达到最高，管理更加的科学和便捷。本论文的远程教育网站系统实现了学生端管理、教师端管理、试卷表管理、试题表管理、考试记录表管理、答题详情表管理、在线考试系统管理、公告管理、学生管理、老师管理、管理员管理等功能。系统用到了关系型数据库中MYSQL作为系统的数据库，有效的对数据进行安全的存储，有效的备份，对数据可靠性方面得到了保证。并且程序也具备程序需求的所有功能，使得操作性还是安全性都大大提高，让远程教育网站系统更能从理念走到现实，确确实实的让人们提升信息处理效率。
