Nice one Phil! It makes the distinction very clear.

I like this one from The Register:

Big Data is any data that doesn't fit well into tables and that generally responds poorly to manipulation by Structured Query Language (SQL).

[T]he most important feature of Big Data is its structure, with different classes of Big Data having very different structures.

With that definition, we can start to look at examples. A Twitter feed is Big Data; the census isn't. Images, graphical traces, Call Detail Records  (CDRs) from telecoms companies, web logs, social data, RFID output can all be Big Data. Lists of your employees, customers, products are not.

Let's here some of your own definitions. If you had to make a dictionary entry, what would you write about big-data?

@kicheko, true.  A short description packs a lot of complications here.

Ariella, - So true though what he says. Big-data is just lots of data in different terms. Funny though how as soon as someone found the shortest word to refer to lots of data, it became complicated. I believe that most of the difficulty in explaining big-data is in actual sense difficulty in understanding the tools of handling big-data and their dynamics

@Noreen: Excellent topic.  Defining big data is something I pondered on while penning my recent musings on the definitions of other industry terms.  I like the statement about 'big data' being relative.  It's kind of like calling something 'new'.  Well, it's new now, but for how long?  And when it's not anymore, will we take the new off?  In my first analytics job, I worked on a SAS server that had 800 GB of disk space.  We thought that was a ton.  Now you can buy mulitple TB drives off the shelf at Staples.  Is 800 GB still 'big'?  Nope.  Exa-, zetta- and yotta- are big, for now, but for how long?

Florissi predicted the era of big-data we will trigger changes similar to the ones that occurred during the Industrial Revolution,

It's really amazing to think of the changes big-data could usher in -- comparing it to the industrial revolution is mind-boggling!

I rather like the expression, "we got a whole lotta data." It almost sounds like a song.
