Big data is growing up

May 8, 2014 | by Dai Clegg, VP product marketing, Acunu
I recently started researching a longer piece I’m writing about big data architectures, and I realized something: big data is growing up. It has moved rapidly from a collection of critical, but over-hyped technologies disrupting core relational database market segments to an emerging eco-system to...

A revolution in the visualization of data

March 3, 2014 | by Dai Clegg, VP product marketing, Acunu
We're collecting more data, from more sources, in more formats. The opportunities to derive insight from all these new sources have exploded, but the essential point is not just to discover, identify, categorize and summarize the data—it is also important to communicate it, and that so often means...

The 'Museum Clickers' of Big Data

December 3, 2012 | by Dai Clegg, VP product marketing, Acunu
When thinking of use cases for big data analytics, consider your need for immediacy. Do you have the need to know now, not just the ability to know now? In other words, would you do something differently at that moment if you knew the answer immediately?

Real-time Analytics - Low Latency and High Velocity

October 5, 2012 | by Dai Clegg, VP product marketing, Acunu
Well there’s real-time, then there’s real-time, then there’s real-time.  As so often with me, this post was first drafted on a plane, and when it comes to in-flight technology, real-time means very real-time. But after that, there’s pretty much a spectrum.  Real-time fraud analytics for a credit...

Crowdsourcing Your Way to Big Data Value

August 21, 2012 | by Dai Clegg, VP product marketing, Acunu
Recently, I was in Nice for a three-day gathering of 150 European IBM Big Data specialists. Looking around the room at the opening plenary made me think how fast the world of big data is moving and how quickly our community is growing. One of the topics that got discussed a lot–in the breaks and in...

Semi-Structured Data Analytics: Relational or Hadoop Platform? Part 2

August 11, 2012 | by Dai Clegg, VP product marketing, Acunu
For some vendors, the only use case for unstructured data is to turn it into structured data to analyze it in a relational database. This is a legitimate use case, especially where you want to analyze in conjunction with relational data, or you want to make it available for what I called “speed of...

What exactly is 'semi-structured' data? How is it different from relational data? And what about 'structured, but not relational' data? Dai Clegg explains the intricacies of semi-structured data and how it fits into relaitonal or Hadoop platforms. Using an example of a telco seeking affinity...

Exploring Uncharted Data: Is there any insight out there?

June 8, 2012 | by Dai Clegg, VP product marketing, Acunu
The biggest table in any Netezza database that I know of has over 600 billion rows!! That’s the claim made by our customer, Catalina Marketing. So although most of the data in the world is not relational, there is a huge amount of relational data and IBM technologies are more than capable of...

Big Data: The Data Velocity Discussion

May 15, 2012 | by Dai Clegg, VP product marketing, Acunu
If there’s more and more data arriving and time isn’t expandingi, then data must be arriving at greater and greater velocity. In my last post I talked about Variety in the Volume, Variety, Velocity triumvirate. There’s more to be said about that, but first I’d like to take a run at Velocity. We’ve...

Big Data: The Data Variety Discussion

May 1, 2012 | by Dai Clegg, VP product marketing, Acunu
We'll start from the very beginning.  It's a very good place to start... Big data is all about Velocity, Variety and Volume, and the greatest of these is Variety. At least it causes the greatest misunderstanding.
