【MongoDB】Serveral common command of MongoDb

In the recent days, since the overwork made me exhaused, on arrival to home I will go to bed, which leads to loss of blogs that should have been written in the past days.

Now  I make a summay to all the commond of operating mongoDB.

First, you should run the mongoDB server. if the following picture exists, it means you has run the mongoDB successfully.

Secondly,after run the mongodb server, next should execute the mongodb client.

thirdly, we input the db.help command, we will find all the method to operate database/

In the above picture, it;s generally used in the development.

Notes, in the mongodb, there is no command like mysql ('create database xxx'), instead use command 'use dbname' to create a new db;

Lastly I set a simple exampe to show usage of some command.
