Where does NoSQL database store data?

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. NoSQL databases often store data in a form that is similar to the objects used in applications, reducing the need for translation from the form the data is stored into the form the data takes in the code. The amount of data in many applications cannot be served affordably by a SQL database. Here are the four main types of NoSQL databases:Document databasesKey-value storesColumn-oriented databasesGraph databases
