We have a transformed approach to the database with MONGO DB. It saves back end developers from the concept of Rows and Columns and introduces documents with a schema with the help of JSON. It is also being called NoSQL.

Why MongoDb?
- It provides easy querying and indexing.
- It can be used to store graphics.
- It bridges the gap between Relational database management system and Key values.
- The documented approach has made it highly available and easily accessible.
- It provides two or more Mongo DB instances.
