NoSQL refers to non-SQL or non-relational database design. It provides an organized way of storing data but not in tabular form (i.e. labelled rows and columns). The common structures adapted by NoSQL databases to store data are key-value pairs, wide column, graph, or document. There are several NoSQL databases used in the data science ecosystem. Examples of NoSQL databases Many NoSQL databases were designed by young technology companies like Google, Amazon, Yahoo, and Facebook to provide more effective ways to store content or process data for huge websites. Some of the most popular NoSQL databases include the following: A NoSQL database enables ad platforms to track user attributes and also access ads to place extremely quickly, increasing the probability of a click.

So, having a sample database that matches your NoSQL database is even more important.

NoSQL is a non-relational database that does not typically use Structured Query Language (SQL) to retrieve information.

High-level data abstractions—moving beyond the "value in a cell" data model, NoSQL systems can provide high-level APIs for powerful data structures.
