Problem: It's not just the vast quantity of data that poses a problem, it's the speed at which data moves. Not being able to capture data fast enough and make good use of that information is a big data problem faced by many organizations.
Solution: Use a variety of tools to capture data, depending on the situation. That helps a platform make use of big data rapidly. Doug Laney at Gartner specifically mentioned databases, computing horsepower, and analytic software for complex event processing.
