MongoDB

• MongoDB is a document-based NoSQL database.
• MongoDB uses MongoDB query language and supports Adhoc queries, Replication, and Sharding.

Replication in Mongo
Replication serves as a very important feature in order to protect data loss from one server, increase the availability of data, and give protection from failures.

Sharding in Mongo DB
Sharding is used by MongoDB to store data across multiple machines. It uses horizontal scaling to add more machines to distribute data and operation with respect to the growth of load and demand.
