Big data is the currency of the new economy. Big data is an evolving term that describes any voluminous amount of structured, semistructured and unstructured data that has the potential to be mined for information. Big data is often characterized by the 3 Vs: the extreme volume of data, the wide variety of data types and the velocity at which the data must be processed. Although big data does not equate to any specific volume of data, the term is often used to describe terabytes, petabytes and even exabytes of data captured over time. But it is not the amount of data that is important, it is what an organization does with the data that matters. Big data can contain a lot of valuable information and can, when gained and analyzed correctly, be a game-changer for your organization. Today's practical applications of big data can be found in data analytics, marketing, fraud detection, government security, election campaigns, real-time predictions, sport transfers and more.
