<p>From the reviews of the first edition:</p> <p></p> <p>"This book covers schema extraction from an Extensible Markup Language (XML) data instance, algorithmic normalization of that schema … and the discussion of relaxing the normalization to effect more efficient retrievals. … Database designers and students are obvious targets for this book … . The book is easy to read, and provides an approach to a very practical contemporary problem. The authors have organized their material for easy reading." (E.A. Unger, Computing Reviews, April, 2005)</p> <p>"Semistructured data are especially applied in web-applications. … The book is written in English. It is recommended to both practitioners and researchers/students, who have to deal with the design and storage organization of semistructured data." (Waltraud Gerhardt, Zentralblatt MATH, Vol. 1076, 2006)</p>
