In IT world, Big data is a collection of data sets so large and complex that it becomes difficult to process using database management tools on-hand. The challenge their is how to capture, curation, storage, search, sharing, analysis and visualization. Creating a database for big data like this is like derivable from analysis of a single large set of related data, as compared to separate smaller sets with the same total amount of data, allowing correlations to be found to “spot business trends, determine quality of research, prevent diseases, link legal citations, combat crime, and determine real-time roadway traffic conditions.
This is a visualization created by IBM. At multiple terabytes in size, the text and images of Wikipedia are a classic example of big data.
Twitter generates somewhere on the order of 12 terabytes of data every 24 hours. The Large Hadron Collider (LHC) produced 13 petabytes of data in 2010. Even Walmart handles more than 1 million customer transactions every hour. Analyzing this torrent of information, whether to quickly spot emerging trends, track the Higg-Boson particle, or accurately identity fraud at the checkout, requires a bit more computational power than MS Access.
