The Rapid Growth of Unstructured Data

In late 2011, IDC Digital Universe published a

report indicating that some 1.8 zettabytes of

data will be created that year. (Source)

In other words, the amount of data in the world

today is equal to:

Every person in the US tweeting three tweets

per minute for 26,976 years.

Every person in the world having more than

215m high-resolution MRI scans a day.

More than 200bn HD movies – which would take a

person 47m years to watch.

Why Big Data

• Key enablers of appearance and growth of Big Data are

–Increase of storage capacities

–Increase of processing power

–Availability of data

–Every day we create 2.5 quintillion bytes of data; 90% of the data in the world today has been created in the last two years alone
