Introduction to Big Data (non-technical) and the importance of Data Science to create meaning.

First of all we define Big Data in the light of the 3 Vs: volume, velocity and variety; next we move on to redefine Big Data, and we touch the topic of a data lake. We envision that Big Data will become mainstream for small organisations as well, what we can do with Big Data, how to tackle Big Data projects, what challenges lie ahead, but what opportunities are there to reap. And of course how important data science is to find the meaning in all the data.

  9. 9. New tools and technologies to store and process all data on a cluster of commodity hardware so that the system acts as one, is resilient and scales linearly. 9 What is Big Data? — revisited
  10. 10. So what? 10 the data lake is a large data pool in which the schema and data requirements are not defined until the data is queried, processed, analysed or delivered as information to the end-user

  13. 13. 13 What does Big Data enable? • Combine data from within and without your organisation • Build new products and services • Analyse all data (e.g. 5TB historic event data at rest in Oracle db)
  14. 14. Big Data is no panacea 14 • First decide what problem you want to solve; pick a real business problem to add immediate value • Start small, the technology is made for linear scalability (a 3-node cluster is a cluster!) • Then become lean: learn through experimentation
  15. 15. Big Data challenges • Beware of hype, Big Data - washing and fad • Tech infancy • IT | Biz • Data is hard • Lack of skills! shameless self plug: BigBoards! 15
  16. 16. Big Data opportunity • Big Data is here to stay • Vendor market is HUGE and will grow massively as Big Data will blend in within the datacenter • However, the Practitioner market can deliver EXPONENTIALLY more value 16
  17. 17. 17 It is time to band together and build these systems that deliver this kind of value for fun for profit for good for Belgium? Call for Action
