MongoDB Create Collection

1.The best thing about MongoDB is that you do not need to create an collection before inserting a document into it. With one command you can insert a document into the collection and MongoDB creates that collection on the fly.

\\Creating the Collection in MongoDB on the fly
db.collection_name.insert({key:value, key:value…})
-----------------------------
-----------------------------
\\Creating collection with options before inserting the documents
db.createCollection(name, options)
