When you insert data in the next step, a collection will automatically be created for you.
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.
 
 
 
To check this has been created:
 
 
 
show collections
 
 
 
Which should return:
 
 
 
<pre color:"blue">
 
db.createCollection('deptCollection', {max: 20})
 
{ "ok" : 1 }
 
</pre>
