What is MongoDB?

We are all aware that data is produced at a rapid rate and in enormous quantities in the modern world. To store this continuously growing amount of data, we require a flexible source that can expand when data generation and storage are high and contract when the opposite is true.

With its adaptable attitude, the MongoDB database solves this issue. Now, what exactly is mongoDB? The following is a typical definition-
"MongoDB is a document database. It stores data in a type of JSON format called BSON(Binary JSON) which is more memory efficient and optimized in terms of data access time".

A record in MongoDB is a document, which is a data structure composed of key-value pairs similar to the structure of JSON objects.
