根据UI设计稿

1.确定功能模块所属集合

2.确定集合字段

UI设计稿每个展示内容对应一个字段
创建于字段
更新于字段
状态字段

最后：先中文，后英文

练习：设置存放学生信息的集合，并插入20条测试数据

1.先中文
集合名称：学生集合
集合字段：编号、学号、姓名、电话、性别、年龄、学历、备注

2.再英文
use school
for(var num=1;num<=20;num++){
	db.stu.insert({
		id:num,
		no:"QF"+num,
		name:"神龙教"+num,
		tel:"111111111",
		sex:"女",
		age:num,
		school:"研究生",
		remark:"富婆"
	})
}

> use school
switched to db school
> for(var num=1;num<=20;num++){
... db.stu.insert({
... id:num,
... no:"QF"+num,
... name:"神龙教"+num,
... tel:"111111111",
... sex:"女",
... age:num,
... school:"研究生",
... remark:"富婆"
... })
... }
WriteResult({ "nInserted" : 1 })
> db.stu.find().pretty()    # .pretty()可以格式化数据
