Summary: Abstract, But If You Make The Connection To Your Business...
Review: you will not be disappointed. The models presented are, as other readers have noticed, highly abstracted, and I believe that Mr. Hay himself would agree. That said, the view he presents assists you as a data analyst with creating data models that are, in fact, more elegant and which do, in fact, more accurately represent the information you're attempting to capture. Despite having developed commercial software since I was in high school, nearly all of it with database components, this book finally gave me the higher-level understanding that I needed.As for criticisms that the book is focussed on relational database technology, for the most part, this is correct. However, as a developer, I believe that the careful business analysis that Mr Hay's approach infers is one area in which current OO practice leaves much to be desired. It doesn't matter if you're an Oracle, DB2 or Cache shop. This book will help you understand your data better.
