  • The Reality of Big Data
  • #beltech2014
  • #1 – What problem are you trying to solve?
  • Most of SME’s problems aren’t Big Data, it’s just data.
  • Without a question you are wasting your time.
  • #2 – Data will need cleaning
  • Roughly 80% of your data project will be getting the data into shape before processing.
  • Btiany Spears
  • #3 – Hadoop, on it’s own, will NOT give you the answers.
  • #3 – Hadoop, on it’s own, will NOT give you the answers. (The Big Data version of “putting it in the cloud”)
  • If anyone says, “will Hadoop just give us the answers” or “put it in the cloud”, do this….
  • Spit on one, or both, of their feet and bite your thumb while shouting: “The fig of Spain!”.
  • #4 – Do you actually need Hadoop?
  • A well crafted algorithm may give you more benefit.
  • It’s about knowing the right questions.
  • And refining and refining and refining…..
  • The first run won't work at all The second only makes you wonder The third will have you on your knees.....
  • #5 – Data changes
  • …especially when you don’t own it.
  • If you feel your data has value then retain it.
  • If your data passes over the “creepy line” then definitely retain it.
  • #6 – Skills are in short supply
  • Work with what you have.
  • Play with data, it’s the best way to learn.
  • Collaborate with others to fill the skills gaps.
