Big Data Composition • Massive amounts of data generated daily which cannot be processed with conventional data analysis tools (volume, velocity, variety) – Impossible to store all generated data, 90% real-time surgical video feeds discarded • Scientific, governmental, corporate, and personal – Each generating exabytes/year – 1990s data management challenge solution: low-cost storage, massively parallel processing, data warehouses.

What are Big Data Scientists Saying? • Jim Harris, Data Science Consultant: beware of big data fundamentalism; a need for data philosophers 

• Evelyn Rupert, Goldsmith’s London, Economies and Ecologies of Big Data: (dangerous) normative relation to data; no reality, just representation; data is performative. 

• Grady Booch, IBM Chief Scientist: human and ethical aspects, tremendous social benefits, full life-cycle of data, ineffective legal controls. 

• James Kobielus, IBM Big Data Evangelist: no ‘single version of the truth’; be critical of beautiful data visualizations and data-driven narrative stories.
