This book is aimed at experienced application developers, data engineers,tech enthusiasts, and others who are seeking a well-rounded understanding of the modern database landscape. Prior database experience is not strictly required, but it helps. Each chapter is designed to be taken as a long weekend’s worth of work, split up into three days. Each day ends with exercises that expand on the topics and concepts just introduced, and each chapter culminates in a wrap-up discussion that summarizes the good and bad points about the da tabase. You may choose to move a little faster or slower, but it’s important to grasp each day’s concepts before continuing. We’ve tried to craft examples that exploreeach database’s distinguishing features. To really understand what these databases have to offer, you have to spend some time using them, and that means rolling up your sleeves and doing some work.
