Create a Collection
If a collection does not exist, MongoDB will automatically create the collection when you first store data for that collection.
When you first use MongoDB you will find you have no collections:
show collections
You can, however, create one and set some options:
db.createCollection('deptCollection', {max: 20})
In this case we are going to limit our collection to hold a maximum of 20 documents.
This command should return:
db.createCollection('deptCollection', {max: 20})
{ "ok" : 1 }
To check this has been created:
show collections
Next Step
Inserting data into the collection
