What Is Big Data?

To really understand huge information, it is helpful to get some historic background. Here is Gartner's definition, circa 2001 (that is still the go-to expression): Big information is information which contains better variety arriving in increasing quantities and using ever-higher velocity. This is known as the three Vs. To put it differently, large info is bigger, more complicated data sets, especially from new information sources. These data sets are so voluminous that traditional data processing software simply can't manage them.
