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.

Big Data is about
tools to examine

pools of data
to create information & knowledge from it.

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 silowhich creates an even bigger lock-in effect for the customer.

Big Data: An example
Youtube: 3TIER, http://www.youtube.com/watch?v=iqSNXZL8GFk
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.

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.

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 causeswaking 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

Centralized vs. Decentralized
centralized decentralized distributed
ETL

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

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
