How does NoSQL database store data?

Question

NoSQL databases store data in documents rather than relational tables. Accordingly, we classify them as "not only SQL" and subdivide them by a variety of flexible data models. Types of NoSQL databases include pure document databases, key-value stores, wide-column databases, and graph databases.

Can NoSQL store structured data?

NoSQL databases can store structured, semi-structured and unstructured data. Their main advantages focus on semi-structured (JSON, XML, not all fields are known) and unstructured. But, you can safely store BLOB in a RDBMS, e. g., Oracle Database and many others relational databases.

In which format data is stored in NoSQL?

The format used could be JSON, XML, YAML etc. The JSON format is the format of choice for NoSQL databases, and for good reason. A JSON document is simply more compact and more readable. JSON (JavaScript Object Notation) is a data representation format formulated by the JavaScript programming language.

How data is stored in the MongoDB database?

In MongoDB, data is stored as documents. These documents are stored in MongoDB in JSON (JavaScript Object Notation) format. JSON documents support embedded fields, so related data and lists of data can be stored with the document instead of an external table. JSON is formatted as name/value pairs.
