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）。

（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
