Main Page >> MongoDB >>MongoDB Workbook >> Create Complex Collection
Create a Collection
This time we will create a collection in advance and add some nested documents to it.
Check what collections you have already:
show collection
Now create a new one called deptCollection 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
