Too many encounters with Big Data happening these days -- through articles, newsletters, and even books. Big Data is the Big Buzz. During JavaOne 2013 Hyderabad, I realized that using the words “Big Data” in the title of your presentation is a sure way of drawing crowds; in fact, one of the sessions was about jvm tuning but was named Big Data and performance or some such thing, and needless to say the room was full and folks had crammed even the standing space. Intellectual dishonesty, I abhor. The starting point for getting into Big Data space is of course data analysis, which is but a fancy word for applying stuff that you learn in college courses on statistics. So I wanted to get my hands on to a few things in data analysis. As is my habit, to take a dive into a subject, I first scour for books. Online, of course.
