二，项目简介

使用旧方法对高校宿舍信息管理系统小程序的信息进行系统化管理已经不再让人们信赖了，把现在的网络信息技术运用在高校宿舍信息管理系统小程序的管理上面可以解决许多信息管理上面的难题，比如处理数据时间很长，数据存在错误不能及时纠正等问题。这次开发的高校宿舍信息管理系统小程序对报修管理、字典管理、试卷管理、试卷选题管理、试题表管理、考试记录表管理、答题详情表管理、错题表管理、访客管理、公寓管理、公寓收藏管理、公寓学生管理、公寓退宿申请管理、公寓入住申请管理、缴费管理、留言管理、宿舍管理员管理、调宿申请管理、卫生管理、学生管理、管理员管理等进行集中化处理。经过前面自己查阅的网络知识，加上自己在学校课堂上学习的知识，决定开发系统选择小程序模式这种高效率的模式完成系统功能开发。这种模式让操作员基于浏览器的方式进行网站访问，采用的主流的Java语言这种面向对象的语言进行高校宿舍信息管理系统小程序程序的开发，在数据库的选择上面，选择功能强大的Mysql数据库进行数据的存放操作。高校宿舍信息管理系统小程序的开发让用户查看公寓信息变得容易，让管理员高效管理公寓信息。
