python+mysql实现个人论文管理系统

Python  /  管理员 发布于 7年前   195

本文实例为大家分享了python mysql个人论文管理系统的具体代码，供大家参考，具体内容如下

1.mysql数据库建表

在mysql数据库里面建立两个表，分别是用户表和论文表。建表的方式有很多，可以直接用sql语句进行建表，也可以在Navicat里面直接建，在Navicat里面可以清楚的看到我们建表的类型和表中的数据。

上图是用户表的数据类型

上图是论文表的数据类型

上图是论文表的样例

上图是用户表的样例

2.流程实现展示

本次系统的实现主要用到python的pymysql库来连接mysql数据库，用wxpython库来实现可视化界面，通过自己定义的db.py的类库来实现对数据库的增删改查等基本的功能。主体的程序主要用到类的继承来实现整个流程。

1.登录界面展示

2.管理员权限进入系统展示

3.普通用户进入系统展示
