MongoDB is a scalable, high-performance, open source, document-oriented database. It supports a large number of languages and application development platforms.
MongoDB is based on NoSQL databases, which means:
When compared to relational databases, NoSQL databases are more scalable and provide superior performance, and their data model addresses several issues that the relational model is not designed to address.
Data is stored in BSON documents, similar to JSON structures. It may be helpful to think of documents as analogous to rows in a relational database, fields as similar to columns, and collections as similar to tables.
