Migration from a Relational Database to NoSQL

2. Concepts Of Big Data

The emergence of the term Big Data a few years ago and the exponential growth of digital information displays for data sets became so large that it is difficult (or impossible) to treat them with adequate response times through traditional tools.

The notion of “Big” in terms of volume of data varies from one company to another. It relies on a set of technological and technical innovations that profoundly transforms how businesses and individuals generate, transmit, store, and use data. Its purpose is the integration, storage, and analysis of multi-structured data (Franklin, 2015).

This staggering amount of data cannot be collected, stored, managed, and operated by traditional IT solutions combining physical infrastructure and relational databases. In order to find appropriate technological solutions, a first phase of conceptual clarification of Big Data has been imposed, thus study and analysis firms proposed the rule of 3V: Volume, Velocity and Variety.
