The problem is that a math model, like a metaphor, is a simplification. This type of modeling came out of the sciences, where the behavior of particles in a fluid, for example, is predictable according to the laws of physics.
Andrew McAfee, principal research scientist at the M.I.T. Center for Digital Business, led off the conference by saying that Big Data would be "the next big chapter of our Business history.
Big Data, said Professor Brynjolfsson, will "replace ideas, paradigms, organizations and ways of thinking about the world."
The results, according to technologists and Business executives, will be a smarter world, with more efficient companies, better-served consumers and superior decisions guided by data and analysis.

Les bonnes questions à se poser quand on gère un projet de big data "How do you define the problem? What data do you need? Where does it come from? What are the assumptions behind the model that the data is fed into? How is the model different from reality?"
Un nouvel outil de recherche de données : "A new system developed in Co Galway could help make it easier to search data that is stored in a number of different places at once.
The new platform, which is the result of an ongoing collaboration between Fujitsu and NUI Galway's Digital Enterprise Research Institute, offers to quickly sort publicly-available data even if it exists on different websites, in different formats."
"There is, of course, a great deal of discussion about the opportunities big data gives companies for greater customer insight and operational efficiency. But many companies, if not most of them, work in relatively sparse data environments: in emerging markets, B-to-B industries, highly specialized or concentrated markets, and the like. These companies have to be content with what I would call "little data.""
