We could consider this book as a classical one from many points of view. To start with, the book is the third in a series of editions since the first one more than 20 years ago, thus containing the evolution in the field of distributed databases as well as the basic concepts which are not strongly affected by technology evolution. The thorough review of relational databases as well as a discussion of several aspects of distributed systems (as computer networks) in Chapter 2 makes the book highly self-contained, enhancing reading and understanding underlying principles. The book covers all the problems expected to be encountered in distributed databases.\n\n(Párrafo extraído del texto a modo de resumen)
