Our phone knows more about us than we think. It can collect and analyze information about how we move around the city, what posts we like and what applications we use. He will report traffic jams and hurry us to work so that we are not late; will select music to suit our mood and make a list of personal recommendations on what to do during the day. The telephone is no longer a device used to make calls; it is already a means of controlling the world around us. Unnoticed, we have surrounded ourselves with interfaces that create an invisible barrier between man and the environment. Planning, management, communication, everything is now built through these programs and devices. Even human relationships. But how deep is the rabbit hole? Everyone has to figure this out for themselves. This book will help convey the basic principles of designing and creating such interfaces for managing business, society and the world around us through Big Data. Read, enjoy and remember: burning books is illegal.
