一起学MongoDB（五）——数据库设计流程
内容导读
互联网集市收集整理的这篇技术教程文章主要介绍了一起学MongoDB（五）——数据库设计流程，小编现在分享给大家，供广大互联网技能从业者学习和参考。文章包含4204字，纯文字阅读大概需要7分钟。
内容图文
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
