Big data WAS there all along, except that it is getting BIGGER every day.  Used to manipulate data via SAS or plan SQL statements.

With the advancement of technology (data storage, type of storage : audio, image, video or plain text, speed of processing, communication speed etc),  and the available of data.  Witness the proliferation of China video surveillance on the STREETS by LE, they have so much data to scan for possible suspect in question to MATCH.
Or just plain Google image search by us on pictures.

One tool you could use is SAS language, which is popular with any IT department and taught at U or via SAS courses.  Just plain SQL statements will be fine.  I am talking based on Text based, not into image, audio, video big data inquiry which is foreign to me.

I am old timer.
Sorry, SQL, SAS good enough for me.
I could easily tabulate all stock holdings for bank client portfolio to list all the total holdings for each stock with one click and a few hours of processing.  Interesting indeed.  Could use that info to check out day to day stock changes for my insider trading if I have time and money to play with, haha.
