Title: Dry and impossible to read
Product review: It is more like a monologue than a well-organized textbook. The author spent way too many pages in glory details of ER modeling and EER modeling. You might think that it can serve as a good reference book. Wrong! It is impossible to follow the logic (or lack of) of the authors. They would go pages of plain text without and summary, highlights, or bullet points. In some of the figures the authors intentionally planted several errors (without marking them), and you'd stare at the figure for sometime and get confused, and need to go the tedious explanation to see what is going on. Who in the right mind would write a textbook like that?As for the non-traditional divergences brought up by another reviewer, this is a textbook that is supposed to be about standardized and well-accepted modeling and designs so you can communicate with others, why do you ever want to learn some non-traditional divergences that only the authors use?
