Big Data

A colorful term used to describe large sets of structured, semi-structured and unstructured data. Data sets are continually increasing in size and may grow too large for traditional storage and retrieval. Data may be captured and analyzed as it is created and then stored in files. Big data is often described as high volume, high velocity, high variety, and high veracity -- the 4 Vs. Increasing storage and use of machine data is a major contributor to the big data phenomenon.

In 2001, Doug Laney, then at the META Group, defined big data in a report titled “3-D Data Management: Controlling Data Volume, Velocity and Variety.” Barry Devlin of 9sight Consulting identifies four categories of information that constitute big data: 1. Machine-generated data, 2.Computer log data, 3. Textual social media information, and 4. Multimedia social and other information.
