NoSQL encompasses a wide variety of different database technologies and were developed in response to a rise in the volume of data stored about users, objects and products, the frequency in which this data is accessed, and performance and processing needs. Relational databases, on the other hand, were not designed to cope with the scale and agility challenges that face modern applications, nor were they built to take advantage of the cheap storage and processing power available today.


What is NoSQL

NoSQL is not the name of any particular database instead it refers to a broad class of non-relational databases that differ from classical relational database management systems (RDBMS) in some significant aspects, most notably because they do not use SQL as their primary query language, instead providing access by means of Application Programming Interfaces (API).

Understanding CAP theorem

Despite the high demand in recent years for massively distributed databases with high partition fault-tolerance, the CAP theorem stipulates that it is actually impossible for a distributed system to provide consistency, availability and partition fault-tolerance guarantees simultaneously; a distributed system can satisfy at most any two of these guarantees at the same time, but not all three. Let's understand this in detail.
