The book Distributed Database Systems authored by Chhanda Ray is all about the need for managing large volumes of data leading to the evolution of database technologies. In recent years, the amount of data handled by a database management system has been increasing continuously, and is no longer unusual for a DBMS to manage data sizes of several hundred gigabytes to terabytes.

This book focuses on the key concepts of the distributed database technology. In this book, all concepts related to Distributed DBMS such as distributed database fundamentals, distributed database design, distributed DBMS architectures, distributed transaction management, distributed concurrency control, deadlock handling in distributed system, distributed recovery management, distributed query processing, data security and catalog management in distributed system and related concepts are briefly presented.

Distributed Database Systems discusses the recent and emerging technologies in the field of distributed database technology. The material is up-to-date, highly readable, and illustrated with numerous practical examples. The popular distributed database systems, SDD-1 and R*, have been included.

Chapter 1 presents an overview of relational databases. Chapter 2 introduces the evolution of distributed database technology and some key concepts of parallel database systems. It mainly focuses on the benefits of parallel databases and different types of architecture for parallel database systems. Chapter 3 elucidates the benefits and limitations of distributed DBMS over centralized DBMS briefly. Different types of communication networks and different network topologies are briefly described in Chapter 4. Design and architecture of different Distributed databases are presented in chapter 5 and chapter 6.

The book is intended for those who are professionally interested in distributed data processing including students, researchers, application developers, analysts and programmers.

Overall, this book is beneficial for students to leant basic fundamentals of Distributed Architecture of Data Base Management Systems.
