一、項目簡介

英語互助小程序使用Java語言進行編碼，使用Mysql創建數據表保存本系統產生的數據。系統可以提供信息顯示和相應服務，其管理英語互助小程序信息，查看英語互助小程序信息，管理英語互助小程序。

二、系統設計

2.1軟件功能模塊設計

在前面分析的管理員功能的基礎上，進行接下來的設計工作，最終展示設計的結構圖（見下圖）。

2.2數據庫設計

（1）下圖是用戶實體和其具備的屬性。
在這里插入圖片描述
（2）下圖是考試記錄表實體和其具備的屬性。

（3）下圖是興趣小組實體和其具備的屬性。

（5）下圖是答題詳情表實體和其具備的屬性。

（9）下圖是錯題表實體和其具備的屬性。

（10）下圖是學習討論實體和其具備的屬性。

三、系統項目部分截圖

3.1用戶信息管理

如圖5.1顯示的就是用戶信息管理頁面，此頁面提供給管理員的功能有：用戶信息的查詢管理，可以刪除用戶信息、修改用戶信息、新增用戶信息，
還進行了對用戶名稱的模糊查詢的條件

3.2興趣小組管理

如圖5.2顯示的就是興趣小組管理頁面，此頁面提供給管理員的功能有：查看已發布的興趣小組數據，修改興趣小組，興趣小組作廢，即可刪除，還進行了對興趣小組名稱的模糊查詢興趣小組信息的類型查詢等等一些條件。

3.3小組打卡管理

如圖5.3顯示的就是小組打卡管理頁面，此頁面提供給管理員的功能有：根據小組打卡進行條件查詢，還可以對小組打卡進行新增、修改、查詢操作等等。
