1、项目介绍及开发技术

1.1 项目介绍

传统办法管理信息首先需要花费的时间比较多，其次数据出错率比较高，而且对错误的数据进行更改也比较困难，最后，检索数据费事费力。因此，在计算机上安装自习室管理和预约系统软件来发挥其高效地信息处理的作用，可以规范信息管理流程，让管理工作可以系统化和程序化，同时，自习室管理和预约系统的有效运用可以帮助管理人员准确快速地处理信息。

自习室管理和预约系统在对开发工具的选择上也很慎重，为了便于开发实现，选择的开发工具为Eclipse，选择的数据库工具为Mysql，以此搭建开发环境实现自习室管理和预约系统的功能。自习室管理和预约系统是一款运用软件开发技术设计实现的应用系统，在信息处理上可以达到快速的目的，不管是针对数据添加，数据维护和统计，以及数据查询等处理要求，自习室管理和预约系统都可以轻松应对。

1.2 开发技术

Java开发语言、SpringBoot、MyBatisPlus、MySQL数据库、Maven、IDEA开发工具、JDK1.8+、Vue、HTML、CSS、JS。

3、功能截图

用户管理：用户信息的查询管理，可以删除用户信息、修改用户信息、新增用户信息，还进行了对用户名称的模糊查询的条件。

 自习室信息管理：查看已发布的自习室信息数据，修改自习室信息，自习室信息作废，即可删除，还进行了对自习室信息名称的模糊查询 自习室信息信息的类型查询等等一些条件。

公告类型管理： 根据公告类型进行条件查询，还可以对公告类型进行新增、修改、查询操作等等。

 公告信息管理：根据公告信息进行新增、修改、查询操作等等。

4、数据库表结构设计
