Big (unstructured) Data was so-dubbed for lack of a better word. Unfortunately it has suffered the same ambiguity as Kleenex (don't we ask for a Kleenex when we mean any-old-tissue?) or Coke (don't kids ask for a Coke when they really mean any-old-soda, and didn't Coca-Cola have to go on a market scourge to avoid losing the meaning of the word? If you ask for a "Coke" the person at the counter is required to correct your choice if they don't serve it) and don't we use the word "cellophane" to mean - oh wait - cellophane really is a distinct product that never protected the meaning of its name, so it really is lost.
I would honestly rather protect the meaning the term Big Data to mean Big Structured Data without having to say so. Alas, I fear it has already been hijacked forever.
Give me a chicken sandwich, french fries and a Coke, with a side of Data.
We only serve Pepsi, will that be fine?
Yeah sure. And supersize the data to Big Data.
Will that be Big Structured Data or Big Unstructured Data?
What's the difference?
One is like a burger and the other is like a salad.
One we make from a stack with a secret sauce. The other we just toss together at the last minute.
Does it come with dressing?
As much as you can handle.
Make it so.
Unstructured it is. That will be $20.13 at the first window.
