Do Data Lakes Need a ‘Refinement Layer?’

    Four Steps to Ensure Your Big Data Investment Pays Off

    Okay, sure, maybe Gartner has a point about this whole “data lake becoming a data swamp” problem. But a recent Information Age piece proposes that organizations can get around all that — and the need for data scientists — with a “data refinery layer.”

    Haven’t heard of such a thing? Neither have I, and Google seems to only have heard of it twice, including this article and an unsourced Word document.

    “As data is consolidated, the refinement layer would process, evaluate, correlate and learn from the information passing through it, essentially generating additional insights and information from the data, and also linking to the aforementioned applications to drive value,” the article explains.

    That sounds wonderful. Let’s do it! The problem is, after reading the article, I’m still not exactly sure what it is or if it exists or if it could exist.

    This piece says it’s by Ben Rossi, but if you read to the bottom it’s “sourced from Matti Aksela, Comptel.” That’s a niche company that focuses on building customer interaction automation systems for telecoms. Apparently, refinery data layers won’t be on discount during today’s sales.

    So why am I sharing this? I’ve been researching data lakes and talking with numerous experts (more on that another day), and I realize there’s actually a really good point here.

    While there’s some heated debate over the usability and merit of data lakes, large companies are building them for legitimate use cases. Sensor and other Internet of Things data will need to go somewhere, and there are already successful use cases for network intrusion detection and security.

    So the real question is how we make them useful more broadly and, ultimately, that’s going to require abstraction layers. One of the benefits of a data lake is supposed to be less data integration work, but wherever there are layers, there seems to be middleware.

    Data Lakes

    We’ll also probably hear a lot of different names for the same tools along the way. That’s just how tech happens.

    If data tech history teaches us anything, we can expect that industry-specific vendors will pioneer the first drafts of these tools. So, the piece is worth a read to see what technologists are thinking as they try to solve this problem.

    In the meantime, a more practical read for the weekend might be Forbes’ recent article, “3 Major Mistakes Companies Make With Big Data And How To Fix Them.” It’s written by Erik Severinghaus, founder and CEO of digital marketing personalization company SimpleRelevance. Severinghaus discusses more immediate solutions for squeezing business value from Big Data, including the four roles you must have on your Big Data team.
