ENTRIES TAGGED "data problems"

Big data is dead, long live big data: Thoughts heading to Strata

The biggest problems will almost always be those for which the size of the data is part of the problem.

A recent VentureBeat article argues that “Big Data” is dead. It’s been killed by marketers. That’s an understandable frustration (and a little ironic to read about it in that particular venue). As I said sarcastically the other day, “Put your Big Data in the Cloud with a Hadoop.”

You don’t have to read much industry news to get the sense that “big data” is sliding into the trough of Gartner’s hype curve. That’s natural. Regardless of the technology, the trough of the hype cycle is driven by by a familiar set of causes: it’s fed by over-agressive marketing, the longing for a silver bullet that doesn’t exist, and the desire to spout the newest buzzwords. All of these phenomena breed cynicism. Perhaps the most dangerous is the technologist who never understands the limitations of data, never understands what data isn’t telling you, or never understands that if you ask the wrong questions, you’ll certainly get the wrong answers.

Big data is not a term I’m particularly fond of. It’s just data, regardless of the size. But I do like Roger Magoulas’ definition of “big data”: big data is when the size of the data becomes part of the problem. I like that definition because it scales. It was meaningful in 1960, when “big data” was a couple of megabytes. It will be meaningful in 2030, when we all have petabyte laptops, or eyeglasses connected directly to Google’s yottabyte cloud. It’s not convenient for marketing, I admit; today’s “Big Data!!! With Hadoop And Other Essential Nutrients Added” is tomorrow’s “not so big data, small data actually.” Marketing, for better or for worse, will deal. Read more…
