Quick and easy book to read is a journalistic vision of Big Data. The basic concepts are well explained in a simplified but ultra "idealistic" view of Big Data. Not necessarily read if you know and have reflected particularly on the subject N = all, the absolute dictated correlations, blind faith in the "what" and "why not" the causal past to predict the future, the will of a storage all in the absolute is a little credo of this book that repeats the file to pages based on examples but it's interesting in the long ennoyeux .... After this is the lack of relativity which is annoying, lack of critical reflection. We would have liked more from journalists. To offer still your grandmother so she finally understands what you're working.
