What is NoSQL?

A NoSQL (Not only SQL) database offers a method for storing and retrieving data without using the traditional approaches of tabular relations as used in relational databases. This approach uses other NoSQL models such as Document Database, Key-value Store, and so on. This approach was selected for its simple construction, high scalability, and abundant access controls.

What are stateful and stateless architectures?

A stateful architecture allows the user to store the state of each session for further use. The stored status is retrieved to provide a reference point for future transactions. The stateful protocol enhances the performance of the sessions as it stores information from the previous sessions that helps future transactions. Here in this case memory is included as a part of the server to store the data.

In stateless architecture, the stateless protocol neither stores nor refers to the previous transaction. This architecture does not use any additional resources. As a result, in some cases, some functions will not be carried out due to a lack of availability of information.
