1Velocity2BIG DATATHE THREE VS OF BIGDATAVolume.The amount of data matters.Withbig data, you’ll have to processhigh volumesof low-density,unstructured data. This can bedata ofunknown value, such as Twitter datafeeds, clickstreams on a webpage or amobile app, or sensor-enabledequipment. For some organizations, thismight be tens ofterabytes of data. For others, it may behundreds of petabytes.Velocity.Velocity is the fast rate at whichdatais received and (perhaps) acted on.Normally, the highest velocity of datastreams directly into memory versus beingwritten to disk. Some internet-enabledsmart products operate in real time ornear real time and will requirereal-time evaluation and action.Variety.In today’s big data world, datacomes in new unstructured data types.Unstructured and semi-structured datatypes, such as text, audio, and videorequire addition preprocessing to derivemeaning andsupport metadata.

7THE VALUE—AND TRUTH—OF BIG DATASince 2001, two more Vs have becomeapparent:valueandveracity. Data hasintrinsic value. Butit’s of no use until thatvalue is discovered.Equally important: How truthful is your data—andhow much can you rely on it?Today, big data has become capital. Thinkof some of the world’s biggest techcompanies. A large part of the value theyoffer comes fromtheir data, which they’reconstantly analyzing toproduce moreefficiency and developnew products.Recent technological breakthroughs haveexponentially reduced the cost of datastorage and compute, making it easier andless expensiveto store more data than everbefore. With anincreased volume of big datanow cheaper and more accessible, you canmake more accurate and precise businessdecisions.Finding value in big data isn’t onlyabout analyzing it (which is a wholeother benefit). It’s an entire discoveryprocess that requires insightfulanalysts, business users, andexecutives who ask the right questions,recognize patterns, make informedassumptions, and predict behavior.
