Data manipulation

Hilbert and Lopez identify the exponential pace of technological change. Machines application specific capacity to computers information per capita roughly doubled every 14 months between 1986 and 2007 the per capacity of the world's general-purpose computers doubled every 18 months during the same two decades. The global telecommunication capacity per capita doubled every 34 months.The world's storage capacity per capita required roughly 39 to 40 months to double (every 3 years and per capita broadcast information has doubled every 12 years.

Massive amounts of data stored worldwide every day unless it can be analysed presented effectively it essentially resides in what have been called data tombs data archives that are seldom visited. To address that issue, the field of data mining  which can be defined as the process of discovering interesting patterns and knowledge from large amounts of data emerged in the late 1980's.
