Let's step back to the year 1978. Sony introduces hip portable music with the Walkman Illinois Bell Company releases the first mobile phone Space Invaders kicks off the video game craze & William Kent writes this book. We have made amazing progress in the last four decades in terms of portable music mobile communication & entertainment making devices such as the original Sony Walkman & suitcase-sized mobile phones museum pieces today. Yet remarkably the book Data & Reality is just as relevant to the field of data management today as it was in 1978. This book gracefully weaves the disciplines of psychology & philosophy with data management to create timeless takeaways on how we perceive & manage information. Although databases & related technology have come a long way since 1978 the process of eliciting business requirements & how we think about information remains constant. This book will provide valuable insights whether you are a 1970s data-processing expert or a modern-day business analyst data modeller database administrator or data architect. This 3rd edition differs substantially from the first & second editions. Data modelling thought leader Steve Hoberman has updated many of the original examples & references & added his commentary throughout the book including key points at the end of each chapter. The important takeaways in this book are rich with insight yet presented in a conversational & easy-to-grasp writing style. Here are just a few of the issues this book tackles: Has business intelligence" replaced "artificial intelligence"? Why is a maps geographic landscape analogous to a data models information landscape? Where do forward & reverse engineering fit in our thought process? Why are we all becoming "data archaeologists"? What causes the communication chasm between the business professional & the information technology professional in most organisations & how can the logical data model help bridge this chasm? Why do we invest in hardware & software to solve business problems before determining what the business problems are in the first place? What is the difference between oneness sameness & categories? Why does context play a role in every design decision? Why do the more important attributes become entities or relationships? Why do symbols speak louder than words? Whats the difference between a data modeller a philosopher & an artist? Why is the 1975 dream of mapping all attributes still a dream today? What influence does language have on our perception of reality? Can we distinguish between naming & describing?"
