  13. 13. As defined by Forrester the Big Data consists of four dimensions - the so-called 4V: • volume - amount of the data • variety - variety of the data • velocity - rate of incoming new information and analysis • value - value of the data
  14. 14. Volume Volume Big Data applies to large datasets (measured in terabytes or petabytes).
  15. 15. Variety These data come from different sources, which may be inconsistent with each other.
  16. 16. Velocity Data analysis is carried out in time close to real.
  17. 17. Value From the whole mass of irrelevant information Big Data extracts the most important.
  18. 18. Thus Big Data analyzes variety of essential information stored in different datasets.
