NoSQL database:
Written as NoSQL, is the acronym for No SQL, Non-SQL, Not only SQL, or No or Non Structured Query language DataBases (DBs). It is a non-relational database without any tabular relations used in it. It is used as an alternative database solution other than a relational database. In these databases, data is placed in tables with data schema designed before the database's design. It is not a structured database but distributed.

NoSQL databases basically are meant to store, retrieve, manipulate, and index data. It supports the key-value store, document store, graph databases, and BigTable.

The types of applications a NoSQL database would be preferred over a relational database are:
Many web and mobile applications are developed using the NoSQL database in the backend. It is used to work with a large distributed data set. It is used for modern software and application development. It is used instead of relational or SQL databases where SQL DBs cannot address or fit as a solution for the problems. It is used where the use case, problems, or software or applications would have to designed, implemented, developed, built and solved with varying schema or not fixed schema, requires avoiding joins, and requires to scale. It simple overcomes the limitations or shortcomings of SQL DBs. It is also used for Big Data applications. It is used in applications that require storing extremely large data.

A NoSQL database used in the real world:
Amazon DynamoDB is a NoSQL database solution from Amazon Web Services (AWS) public cloud service provider. It is popular and is used in the real world and real-time web and mobile apps and usages use cases. In fact, it is a serverless database solution. It is a fully managed, automatically scaling, and continuously backing your data up solution. It is a better and highly scalable, secure, flexible, reliable, fast database providing reliable performance. It is used to design tables for apps used on mobile devices and even on desktops and laptops.

Other names for NoSQL Database are MongoDB, Apache Cassandra, Apache CouchDB, etc.

The database design process for noSQL databases is different from one for relational (SQL) databases. As we learned noSQL database does not require to have a predefined structure, except of creating a list of databases and the list of collections. Some of the noSQL databases (like MongoDB) allow to define certain rules that will define what should be the structure of the acceptable documents for each collection. As you may recall, when you need to store multiple data points in...
