The Reality of BigData - slides for the keynote at Beltech2014 (4th April 2014) in Belfast.

1. The Reality of Big Data

2. #beltech2014

3. #1 – What problem are you
trying to solve?

4. Most of SME’s problems aren’t
Big Data, it’s just data.

5. Without a question you are
wasting your time.

6. #2 – Data will need cleaning

7. Roughly 80% of your data project
will be getting the data into shape
before processing.

8. Btiany Spears

9. #3 – Hadoop, on it’s own, will
NOT give you the answers.

10. #3 – Hadoop, on it’s own, will
NOT give you the answers.
(The Big Data version of “putting it in
the cloud”)

11. If anyone says, “will Hadoop just
give us the answers” or “put it in the
cloud”, do this….

12. Spit on one, or both, of their feet
and bite your thumb while shouting:
“The fig of Spain!”.

13. #4 – Do you actually need
Hadoop?

14. A well crafted algorithm may give
you more benefit.

15. It’s about knowing the right
questions.

16. And refining and refining and
refining…..

17. The first run won't work at all
The second only makes you wonder
The third will have you on your
knees.....

18. #5 – Data changes

19. …especially when you don’t own
it.

20. If you feel your data has value
then retain it.

21. If your data passes over the “creepy
line” then definitely retain it.

22. #6 – Skills are in short supply

23. Work with what you have.

24. Play with data, it’s the best way
to learn.

25. Collaborate with others to fill the
skills gaps.

26. Thank you
