Big Data inahusu kukamata seti kubwa za data ambazo zana za kawaida za database hazina uwezo wa usindikaji kuchambua. Kuhifadhi na kuchambua data nyingi ni zaidi ya nguvu za zana za usimamizi wa database za jadi. Kuelewa zana bora na mbinu za kusimamia na kuchambua seti hizi kubwa za data ni tatizo ambalo serikali na biashara sawa zinajaribu kutatua. Data kubwa hutoka katika maeneo mbalimbali kama vile maandishi, picha, sauti, na video. Biashara hutumia data hii na kuitaja kama analytics ya uingizaji au analytics ya tabia ya mtumiaji. Makampuni kama vile Walmart na Amazon sasa hukusanya data kubwa, ili kuona ni utafutaji gani wateja wao wanaangalia. Fikiria idadi ya wateja na bidhaa hizi nguvu mbili na kiasi cha data yanayotokana.
