What is Big Data?

Big data is the technique or process through which a massive analysis of information is carried out that would not be feasible to analyse with traditional applications such as relational databases.

The data that big data deals with is structured or unstructured data that can arise from various sources such as purchases, credit card payments, internet browsing, phone calls, interactions on social networks, medical data, and a long etcetera.

The application of big data techniques can make it possible to take advantage of the data collected to obtain knowledge and help make strategic decisions.
