O’Reilly Radar: What is Data Science?

June 3, 2010 By brenda michelson

Mike Loukides has an excellent piece on O’Reilly Radar entitled “What is data science?” In the article, Loukides covers making data products, the data lifecyle, working with data at scale (Big Data), story telling and data scientists.

Throughout the article, Loukides introduces the reader to many data science concepts, tools, experts and skills.

Calling out several items, I love the “data exhaust” term:

“These recommendations are “data products” that help to drive Amazon’s more traditional retail business. They come about because Amazon understands that a book isn’t just a book, a camera isn’t just a camera, and a customer isn’t just a customer; customers generate a trail of “data exhaust” that can be mined and put to use, and a camera is a cloud of data that can be correlated with the customers’ behavior, the data they leave every time they visit the site.”

I think this “make lemonade” sentiment on data quality is crucial:

“Once you’ve parsed the data, you can start thinking about the quality of your data. Data is frequently missing or incongruous. If data is missing, do you simply ignore the missing points? That isn’t always possible. If data is incongruous, do you decide that something is wrong with badly behaved data (after all, equipment fails), or that the incongruous data is telling its own story, which may be more interesting? It’s reported that the discovery of global warming was delayed because automated data collection tools discarded readings that were too low 1. In data science, what you have is frequently all you’re going to get. It’s usually impossible to get “better” data, and you have no alternative but to work with the data at hand.”

The big data definition is excellent. It’s about the problem, not the (product) solutions:

“The most meaningful definition I’ve heard: “big data” is when the size of the data itself becomes part of the problem. We’re discussing data problems ranging from gigabytes to petabytes of data. At some point, traditional techniques for working with data run out of steam.”

And the information platforms / dataspaces concept ties to my active information tier:

“What are we trying to do with data that’s different? According to Jeff Hammerbacher 2 (@hackingdata), we’re trying to build information platforms or dataspaces. Information platforms are similar to traditional data warehouses, but different. They expose rich APIs, and are designed for exploring and understanding the data rather than for traditional analysis and reporting. They accept all data formats, including the most messy, and their schemas evolve as the understanding of the data changes.”

If you want to learn something today, read the article. Then bookmark it for future reference.

Come to my session at IBM Innovate: Smarter Business Planning and Analysis: Business Architecture as a Foundation

June 2, 2010 By brenda michelson

Are you going to IBM Innovate?  The Rational Software Conference.  Then plan to attend my session on Wednesday afternoon!  I’m speaking with IBM’s Robert Shields on Business Architecture as a Foundation to Business Planning, Analysis and Change. 

My part of the presentation, combines themes and outcomes from the SOA Consortium’s EA2010 group, with my own business architecture and enterprise architecture work and point-of-view.  I’ve got something new I’m excited to share.

As always, expect a fair amount of business talk and definite traceability to business motivations. 

If the session is anything like the planning call Robert and I had in May, the session could end with a (positive) call for Enterprise Architecture revolution!

The details:

Session: EAM-2259: Smarter Business Planning and Analysis: Business Architecture as a Foundation
Date/Time: Wed, 9/Jun, 03:00 PM – 04:00 PM
Room: Dolphin – Oceanic 7
Co-presenter(s): Robert Shields, IBM, Senior Market Manager, Enterprise Architecture, Brenda M. Michelson, Elemental Links

Hope to see you next week!

On Dave Linthicum’s Podcast discussing top Cloud Computing Stories for May

June 1, 2010 By brenda michelson

Each time I do a podcast, I can’t help but wonder, “Did I sound as though I had a clue?  Or, like a rambling fool?”.  Well, I guess I exhibited somewhat of a clue on Dave Linthicum’s post Cloud Connect podcast, because he invited me back to discuss top cloud computing stories for May.  We recorded Friday morning, before I headed to the closing keynotes of IT Forum. 

In choosing “top stories”, there weren’t any guidelines.  Just 3 cloud computing stories we found interesting or important for the month of May.  The only rule, was no sharing beforehand. 

As for the results, we had one story in common, two mainstream stories (one each) and two wildcards (one each).  The format was fun, so we’ll do another at the end of June.

I haven’t listened to it, so I’m not sure if my brain freeze trying to find the word “cannibalize” is in, or on the cutting room floor.

To listen to the podcast (16 minutes or so), go here.
