Data usage every minute
    With every website browsed, status shared, and photo uploaded, we leave a digital trail that continually grows the hulking mass of big data.

    So what ? What am I supposed to know about all this ?
    From user perspective, you are not supposed to know anything. You are free to use Facebook, Twitter, Youtube or any other website you like to use. But from a developer's perspective, you have to know a little about these statistics. So that you can relate things when the term Big Data comes to application and you have to handle it in your code.
    OK, but what if I don't have to deal with Big Data in my application. Cause I know, my application is a small one and it has only a hundred customer and will not grow more than that. The data size will never reach more than a few GB and I am not interested to know what Facebook/Twitter/Youtube does for me.
    Well, then you are free to ignore, choice is yours.

    So, what am I supposed to get here ?Very elementary knowledge of Big Data, a little on the lack of processing Big Data in RDBMS, basic idea of NoSQL evaluation, difference between NoSQL and RDBMS and very basics of Big Data processing.
    OK, after that ?
    If you are interested in Big Data, you can grow up you knowledge from Very Basic to Vary Advanced and I am really no one to tell you how to do that. Its solely depends on you how and where to do that.
