I ordered this book from the used book store link on the product home page. The seller claimed that this book was 'Like New'. I don't know how they distinguish New and 'Like New'. This book is absolutely new and it even has the wonderful smell of a new book! The contents of the book speak for themselves. This is a must have for anyone even remotely involved in Data Modeling. The concepts here are so fundamental that most popular ERP systems today use these concepts.
