Big Data Must Get Smaller
The business goals must dictate the analytics, and the analytics call for specific types of data to meet the goals, and the supporting datasets should be in "analytics-ready" formats. Not the other way around, where businesses are dictated by the limitations of analytics, and analytics are hampered by inadequate data clutters. That type of business-oriented hierarchy should be the main theme of effective data management, and with clear goals and proper data strategy, you will know where to invest first and what data to ignore as a decision-maker, not necessarily as a mathematical analyst. And that is the first step toward making the Big Data smaller. Don't be impressed by the size of the data, as they often blur the big picture and not all data are created equal.
