(More customer reviews)Bagui and Earp's "Database Design Using Entity-Relationship Diagrams" is a very well written book. It's clear, concise, and well laid out. It also meets their intended audience and intent. From page xiii of the Preface:
"This book is intended to be used by database practitioners and students for data modeling. It is also intended to be used as a supplemental text in database courses, systems analysis and design courses, and other courses that design and implement databases."
And, from page xvii of the Introduction:
"This book was written to aid students in database classes and to help database practitioners in understanding how to arrive at a definite, clear database design using an entity relationship (ER) diagram."
The only reasons I give it a rating of four stars out of five instead of five stars out of five are purely a matter of taste. First, there's not a lot of breadth to this material. So, I'm not all that certain that a whole book is warranted (it really should be covered in full-fledged database books). Second, the majority of the book focuses on "Chen-like" ER diagrams because they are well-used and implementation independent (which is good reasoning). But, I'm pretty sure that most databases are relational nowadays, so more coverage in the vein of the last chapter (the Barker-like relational ER model) would be a good thing. If I could give the book four and one half stars, I would (it's really that good). But, since I can't, four stars will have to do. If you decide you really need a supplemental text in ER Diagrams, you can't go wrong with this book.

They are also well-known for being difficult to master. With Database Design Using Entity-Relationship Diagrams, Second Edition, database designers, developers, and students preparing to enter the field can quickly learn the ins and outs of ER diagramming.Building on the success of the bestselling first edition, this accessible text includes a new chapter on the relational model and functional dependencies. It also includes expanded chapters on Enhanced Entity Relationship (EER) diagrams and reverse mapping. It uses cutting-edge case studies and examples to help readers master database development basics and defines ER and EER diagramming in terms of requirements (end user requests) and specifications (designer feedback to those requests).Describes a step-by-step approach for producing an ER diagram and developing a relational database from itContains exercises, examples, case studies, bibliographies, and summaries in each chapter Details the rules for mapping ER diagrams to relational databasesExplains how to reverse engineer a relational database back to an entity-relationship modelIncludes grammar for the ER diagrams that can be presented back to the userThe updated exercises and chapter summaries provide the real-world understanding needed to develop ER and EER diagrams, map them to relational databases, and test the resulting relational database. Complete with a wealth of additional exercises and examples throughout, this edition should be a basic component of any database course.
