Big Data refers to a large set of data too complex to be handled by conventional database management tools. It's data that exists beyond your web analytics, ERP, or CRM databases. It often exists outside of your organization, think of customer sentiment and social sharing data owned by Facebook, Twitter and Pinterest, or competitive pricing data from comparison shopping engines.
Without Big Data, it's impossible to get a comprehensive cross-touchpoint view of your customer, and fully understand customer behavior in order to make business decisions in real-time. (Even with Big Data, it's still very difficult to achieve!)
