Justin Rowlatt, BBC World Service, explores how Big Data is not just a whole lot more thank the old “small” data, but a transformative technology that is set to change the way we do everything. From Formula 1 racing to targeted retail, the effective use of data is going to be a basis for competition going forward and a necessary addition to the toolkit of every company. Damian Black, SQLstream CEO joins Michael Chui of management consultants McKinsey in a talk about how the torrent of data digital technology is creating can be used, and explains why all this data could allow companies and governments to learn all sorts of secrets about us all (which is, it seems, not all that bad).
