What is MongoDB

MongoDB is an open-source document database that belongs to a family of databases called NoSQL – not only SQL and provides high performance, high availability, and automatic scaling. Its document-oriented data model makes it easier to split up data across multiple servers.

In MongoDB, records are documents that behave a lot like JSON objects in JavaScript but use a variant called Binary JSON (BSON) that accommodates more data types. The document is a data structure composed of field and value pairs. Values in documents can be looked up by their field’s key and can be easily added/updated anytime which makes Mongo extremely flexible.

This is different than SQL databases, Relational databases, like PostgreSQL, MySQL and, where fields correspond to columns in a table and individual records correspond to rows.
