The author, Thomas Davenport, insists that the "Big Data" represents a major challenge for companies, but his arguments are too general. Even his many references to companies (US) fail to illustrate his point as they remain superficial. Some cases cited dailleurs have nothing to do with the Big Data, but are computer applications entirely conventional. Yes, the amount of data available in each business exploded from internal and external sources, including the Internet. Yes, technology now allows exploit, thanks to extraordinary computing power. Yes, there is therefore opportunities or not. Once past these basic observations, I have the impression that the 220 pages Mount learned nothing more except the technological side of the subject (For connoisseurs, Hadoop is quoted extensively) Jattendais else. Laspect ethical or even legal for personal data, is never mentioned: jusquoù, how can we tackle lexploitation and cross-checking of data (social networks, medical records, bank transactions, purchases, travel, phone calls, web browsing,) in a mercantile? Jaurais also liked a "business" approach by business line: Without being exhaustive, what are or what may be the practical applications of Big Data for banks, telcos, retail, logistics, industry, the relationship customers, the development of new products, about their activity? What are the inputs, costs, risks? But this is not addressed, or much too generic. Although we sense the importance of the subject "Big Data" - which is real - but this book is only leffleurer.
