Database Design Using Entity-Relationship Diagrams (Foundations of Database Design, 1)

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.

The book emphasizes how communication between designers and users during design is crucial for the elicitation of targeted data, and for the creation of an understandable ER diagram. The authors describe how to develop an ER diagram, how to map it to a database, and how the resulting database can be tested. This definitive guide is a beneficial component of any database course and is a strong supplemen Bagui and Earp (both computer science, U. of West Florida) present this text designed for use by database practitioners and students for data modeling, and as a supplemental text in database courses, systems analysis and design courses, and similar courses in database design and implementation. Coverage includes steps for the ER (Entity Relationships) approach for conceptual modeling, the grammar for ER diagrams, and the mapping rules to map the ER diagram to a relational database. Sample data have been included with relational database mappings. Distributed by CRC Press. This text explains how to arrive at a definite, clear database design using an Entity Relationship (ER) diagram. It presents the design process using the software-engineering paradigm of requirements and specifications with the ER diagram being at the core of the specification
