17 Oct Big Data: a change of paradigm (Report only in French)

National Academy of Technologies of France (NATF)

Big Data implies a revolution in IT, reaching from technology to applications and practices, enabling the analysis of vast pools of « digital traces ». Data manipulation from smartphones and connected objects opens up new service opportunities and cost reductions of IT-systems. While it is a major issue for sciences, politics and citizens, this report looks at the impact on businesses: mastering these methods permits a new immediacy in customer relationships. Big data is a disruptive data-analysis methodology, replacing classic approaches by iterative loops and using detected patterns for operational effectiveness. It is a new way of massive parallel data-centred programming and of designing algorithms, due to treatment on a myriad of machines, high-performance requirements, and development of algorithms through learning. It is a major challenge and paradigm shift for Governments and companies, deserving strong support in terms of training and awareness.
