Answer 1

Answer:

As explained in When to Use NoSQL Databases, NoSQL databases were developed during the Internet era in response to the inability of SQL databases to address the needs of web scale applications that handled huge amounts of data and traffic.

Companies are finding that they can apply NoSQL technology to a growing list of use cases while saving money in comparison to operating a relational database. NoSQL databases invariably incorporate a flexible schema model and are designed to scale horizontally across many servers, which makes them appealing for large data volumes or application loads that exceed the capacity of a single server.

The popularity of NoSQL has been driven by the following reasons:

1. The pace of development with NoSQL databases can be much faster than with a SQL database.
2. The structure of many different forms of data is more easily handled and evolved with a NoSQL database.
3. The amount of data in many applications cannot be served affordably by a SQL database.
4. The scale of traffic and need for zero downtime cannot be handled by SQL.
5. New application paradigms can be more easily supported.
