Big Data, a reality that goes beyond fiction
Big Data refers to data sets that have become so large that they exceed intuition and human analytical capabilities, even those of traditional database or information management computer tools.
Big Data is the direct consequence of an explosion of information generated through the Internet of People (social networks) and the Internet of Things, which leads to a drastic change of scale. To give you an idea: the volume of digital data created worldwide was estimated to 1.2 zetabytes per year in 2010. According to the IDC (Digital Universe Study of 2014), it will be 44 zetabytes (a zetabyte is 1021 or 1,000,000,000,000,000,000,000,000,000,000,000 bytes) in 2020.
In other words, more data has been created in the last 2 years alone than since the beginning of humanity! In 2020, 1.7 Mb of data will be created every second and for every human being.
