What is Big Data - only examples - iPresso education series. iPresso Academy presents

1. What is
Big Data?
Focus on strategy and ideas,
iPresso will take care the rest.

2. Imagine a car that
can analyze data about road conditions by itself.

3. It knows the degree of the exploitation of
its individual components...

4. …It records driver’s heart rate and breathing frequency...

5. It collects data on its speed and
acceleration.

6. This information allows to
increase driving safety ...

7. ... avoid an accident...

8. ... bypass traffic jams.

9. Those cars are not a dream.
Automotive companies have
started to produce them..

10. Innovative technology which makes it possible
is called

11. It is a rapidly growing
method of data analysis, which is
used in business, local government and politics.

12. How to define Big Data?
This term refers to the collection of data,
which, due to its large-scale,
can not be analyzed
by using traditional tools.

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. Volume
Volume
Big Data applies to large datasets
(measured in terabytes or petabytes).

15. Variety
These data come from different sources, which may be
inconsistent with each other.

16. Velocity
Data analysis is carried out in time close to
real.

17. Value
From the whole mass of irrelevant information
Big Data extracts the most important.

18. Thus Big Data analyzes variety of essential information
stored in different datasets.

19. The result is the knowledge,
which allows to take
the best possible decision.

20. An example of this technology is
The New York City, where mayor Mike Bloomberg
has set up an entity to deal with Big Data.

21. The New York City gathers plenty of diverse information
about the city:

22. ... number of buildings, their condition and type
of business...

23. ...wi-fi hot-spots locations...

24. ... the number of crimes in different areas...

25. ... population in a given area and its
ethnicity...

26. ... taxes paid by them and
schools their children go
to.

27. All the information (and a plenty of other) is contained
in many different, inconsistent data sets.

28. The use of Big Data - by combining information and
analysis - allows to draw conclusions.

29. As a result, the detection rate of illegal tobacco selling
shops doubled …

30. … the process of removing trees damaged by Hurricane
Sandy was accelerated …

31. … building inspectors were
sent to places where there
was a high probability of fires.

32. Big data makes administration of the city more
effective and efficient.
And what are the benefits in other areas?

33. In finance:
minimizing the risk of the loan.

34. In marketing:
better identification of needs.

35. In politics:
helps to achieve
electoral aims.
Barack Obama also uses it.

36. Thus the applicability of the data is so extensive.

37. According to IDC forecasts, Big Data market will grow from
$ 3.2 billion in 2010 to 16.9 billion in 2015.

38. If these predictions come true, Big Data will become a true
technology of the future.
