Big Data

Big data refers to a collection of data sets so large and complex that it becomes difficult to process using on-hand database management tools or traditional data processing applications. That is, beyond current comfort levels. Big data made a splash in 2012, but it is now recognized that “big” is relative, depending on context, amount of data and complexity of the problem. Gartner glibly identified the “3 Vs” of big data--volume, velocity and variety-- which were recently expanded by Inderpal Bhandar to include another 3 Vs: veracity, validity and volatility. Statisticians, and data modellers in general, might also want to include 3 Us: unknowns, uncertainty, and unfamiliarity. Below is a compilation of links related to big data.
