这是本科数据库实验的代码，用java写的。
运行需要下载jdk8和IDEA，然后导入jfoenix和jdbc这两个jar文件。然后安装MySql，创建一个名叫"warehouse"的仓库，
添加两个用户，一个叫"caigou"，密码为"12"，另一个叫"xiaoshou"，密码为"12"。
.rar文件是最后软件的压缩包，其余的是源代码。
This is my database experiment code, writtten by java.
To run the file, you need to install jdk8 and IDEA, also import the jfoenix jar and jdbc jar.
You need to install MySql, create a database named "warehouse" and add two additional users to it: user named "caigou" @ '%' with password "12" and user named "xiaoshou" @ '%' with password "12".
The .rar file is the compressed file of my experiment, the other files are source code.
