The definition of Big Data
The term “Big Data” is a relatively new within the world of data, it gained traction in the early 2000’s. Doug Laney proposed Big Data consisted as being defined by three factors, the 3 V’s;
VOLUME: New sources of information have continued to grow over the years, social media, transactional, and machine data are but a few. Previously storing all of this data would have been difficult. With new technologies like Hadoop this challenge has been somewhat lessened.
VELOCITY: The speed in which data is streamed or captured has increased over the years. Sensor information along with SMART metering are driving the increase in more real time analysis.
VARIETY: As with an increase in the number of sources of information, the format has also changed. Structured information such as numeric data typically held in databases has always been a major component in big data. Now with the social media boom the unstructured data; that is text documents, email, video and audio information, has become a major player in the big data space.
