Answer 
MongoDB uses a flexible, document-oriented data model (JSON-like BSON format). Data is stored as key-value pairs in documents, which are self-contained units of data.
In contrast, relational databases use structured tables with rows and columns, which often require joining tables to retrieve related data. Joins can be computationally expensive and slow.
