Average Reviews:
(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.

Entity-relationship (E-R) diagrams are time-tested models for database development well-known for their usefulness in mapping out clear database designs. Also commonly known is how difficult it is to master them. With this comprehensive guide, database designers and developers can quickly learn all the ins and outs of E-R diagramming to become expert database designers. Because E-R diagrams are so fundamental to database design, this book is also an indispensable text for teaching computer science students the basics of database development.Database Design Using Entity-Relationship Diagrams clarifies E-R diagramming by defining it in terms of requirements (end user requests) and specifications (designer feedback to those requests). The book explains how open communication between designers and end users is critical to developing usable, easy-to-understand E-R diagrams that model both requirements and specifications. The authors explain, in an intuitive, informal manner, how to develop an E-R diagram, how to map it to a database, and how the resulting database can be tested. This definitive guide is a basic component for any database course, and is also an invaluable reference that database professionals can use throughout their careers.introbul>Features
