根据上面描述完成下面问题：
（注意：注意保存脚本，尤其是DDL和DML，以便进行数据还原）
DDL
写出上述表的建表语句。
命令：create table Student(no int,name varchar(14),sex varchar(2),birthday date,class int);
create table Teacher(no int,name varchar(14),sex varchar(2),birthday date,prof varchar(10),depart varchar(10));
create table Course(cno varchar(8),cname varchar(14),tno int);
create table Score(no int,cno varchar(8),degree int);
DML
给出相应的INSERT语句来完成题中给出数据的插入。
命令：
