 ## USCI GUI DataBase Readme
+### start mariadb on OpenSuse 15.3
+```shell
+# 设置数据库服务自启动并，启用数据库
+sudo systemctl enable mariadb
+sudo systemctl start mariadb
+
+# 使用root账户登录数据库
+sudo mysql -u root
+
+```
+然后执行一下sql代码，创建数据库USCT
+```Sql
+-- 创建用户
+CREATE USER 'rc'@'localhost' IDENTIFIED BY 'password';
+-- 修改密码
+SET PASSWORD FOR 'rc'@'localhost' = PASSWORD('123$%^');
+
+-- 查看所有user看是否创建成功
+select user,host from mysql.user;
+
+-- 创建数据库USCT
+create database USCT;
+```
+然后执行以下Table DDL相关的sql，创建表格并插入数据.
+
