Our digital universe is rapidly expanding, and we're collecting the data. We're gathering social media data, machine data, transactional data, and research data. Information from each tweet on Twitter, like on Facebook, and view on Youtube are recorded. Consumption patterns are tracked at superstores, corner stores, grocery stores, and liquor stores. From the quark to the universe, from the Genome Project to the NASA's New Horizons mission, our researchers are recording and storing data. Data collection is everywhere, and it's big.
