MongoDB document is a JSon object and is also called as a record or row in MySQL. We can insert any number of documents in collection. There are two methods for inserting documents into collection:
a)insertOne()
b)insertMany

With insertOne() we can insert a single document at a time. It has single parameter which is an object. The object may be embedded data or normalized data model.

db.collectionName.insertOne({key:value})

With insertMany() we can insert multiple document at a time. It has single parameter which is an array object. The object may be embedded data or normalized data model.

db.collectionName.insertMany([

	{key:value},

  {key:value}])
