It is well known that, at the present, a huge amount of
information, often referred as Big Data, is processed by each
domain of modern society. Big data are well defined by the seven
dimensions: Volume, Velocity, Variety, Variability, Veracity,

systems cannot handle the requirements of high availability,
scalability and reliability emerged with Big Data.
The good news is that we are now in the age of NoSQL

flexible structure and are suited for storing unstructured data
produced in a large scale in various field.
This work outlines the four main types of NoSQL databases and
presents some of their representative solutions.
