About the book: 2017 / In recent years, the topic of “big data” has gained popularity. But many people are unable to cope with even a small amount of data - and, therefore, are unable to make an informed decision. From the book you will learn how to collect, classify, analyze data; use them at work; recognize fraud and correctly interpret information. You need this book if you want to learn - or teach your employees - to make decisions based on accurate information, not dubious forecasts. Published in Russian for the first time.
