4. A brief history of ‚Data‘
1990 2012
Volatility … The information needed today is different from the
information needed tomorrow, next week or next month.
Changes come from everywhere: internal strategy changes,
competitive pressures, new regulatory requirements
Uncertainty … Companies are increasingly drawing on data from outside
their organization. They’re pulling together information
from supply chain partners, from customers, from social
media sites, from websites and public web databases.
Complexity … Decision makers are relying on data buried in spreadsheets,
in emails, in Access databases and in documents.
Ambiguity … Key enterprise data assets are no longer confined to
predictably structured transactional databases and data
warehouses.

5. Big Data: A Definition
Big Data is about
tools to examine
•large
•distributed
•unstructured
•unrelated and
•quickly growing
pools of data
to create information & knowledge from it.

6. Big Data:
Another Definition
Big Data is about
tools that pull together
•large
•distributed
•unstructured
•unrelated and
•quickly growing
pools of data
to create an even bigger and less flexible data silo
which creates an even bigger lock-in effect for the customer.

7. Big Data: An example
3TIER has conducted
feasibility studies
for over 650 wind projects
on 6 continents,
representing over
20GW of production potential.
In 2011 alone,
3TIER conducted risk analysis
that helped secure over $4.1 billion in public and private financing for
utility-scale solar projects in the US, India, and Australia.

8. Hunch: The power of
correlation
Hunch’s Taste Graph is the foundation that powers Hunch’s predictions.
The graph is fast growing, constantly-improving and built upon a massive data structure.

9. Correlation vs. Causation
Sleeping with one's shoes on is
strongly correlated with waking up
with a headache
OR
Sleeping with one's shoes on causes
waking up with a headache?
Show me all drugs
- related to asthma that
- are linked to a curated molecular interaction in the literature
- where the protein is known to cause inflammatory response

10. Centralized vs.
Decentralized
ETL
centralized decentralized distributed
http://www.poolparty.biz/

11. Example: Querying
decentralized systems
How many people work at SWC?
SWC = Semantic Web Company
20 people work
at Semantic Web Company
20 people work at SWC!
No central data hub needed!!!

12. How decentralization can
contribute to cope with VUCA?
Volatility:
Higher agility when managed units are smaller
Uncertainty:
Make use of algorithms based on correlation
Complexity:
Breaking down into smaller modules, crowd-
sourcing and self organization
Ambiguity:
Better understanding of specialities of sub-domains
& local needs
