【如需全文请按文末获取联系】

一、项目简介

英语互助小程序使用Java语言进行编码，使用Mysql创建数据表保存本系统产生的数据。系统可以提供信息显示和相应服务，其管理英语互助小程序信息，查看英语互助小程序信息，管理英语互助小程序。

二、系统设计

2.1软件功能模块设计

在前面分析的管理员功能的基础上，进行接下来的设计工作，最终展示设计的结构图（见下图）。

2.2数据库设计

（1）下图是用户实体和其具备的属性。

（2）下图是考试记录表实体和其具备的属性。

（3）下图是兴趣小组实体和其具备的属性。

（5）下图是答题详情表实体和其具备的属性。

（9）下图是错题表实体和其具备的属性。

（10）下图是学习讨论实体和其具备的属性。

三、系统项目部分截图

3.1用户信息管理

如图5.1显示的就是用户信息管理页面，此页面提供给管理员的功能有：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

3.2兴趣小组管理

如图5.2显示的就是兴趣小组管理页面，此页面提供给管理员的功能有：查看已发布的兴趣小组数据，修改兴趣小组，兴趣小组作废，即可删除，还进行了对兴趣小组名称的模糊查询 兴趣小组信息的类型查询等等一些条件。

3.3小组打卡管理

如图5.3显示的就是小组打卡管理页面，此页面提供给管理员的功能有：根据小组打卡进行条件查询，还可以对小组打卡进行新增、修改、查询操作等等。
