Distributed Database Management Systems: A Practical Approachby Saeed K. Rahimi
Synopses & Reviews
Unique coverage of traditional database theory and current research for building easier-to-mange distributed database systems
A distributed database management system (DDBMS) is a layer of software, implemented on top of existing database management systems, allowing users transparent access to information dispersed across a network. This book addresses the architectural and platform issues on the design and development of a DDBMS, guiding readers in building their own systems in real-world environments.
Distributed Database Management Systems is divided into three units. The first provides a theoretical foundation for understanding the internal processing of the DDBMS available to address these issues. The second unit presents the “state of the practice,” examining the architectural alternatives that practitioners will likely encounter in the real world and the exploring the general requirements for any platform capable of implementing a DDBMS architectural alternative—including those yet to be invented. The final unit focuses on distributed database implementation, examining three platforms suitable for the development of a real DDBMS system—the Java Message Service (JMS), the Java 2 Enterprise Edition (J2EE), and the Microsoft .NET Framework. For each, a “starter kit” is provided (containing a detailed overview and an extensible framework) and discussed in detail.
This book addresses issues related to managing data across a distributed database system. It is unique because it covers traditional database theory and current research, explaining the difficulties in providing a unified user interface and global data dictionary. The book gives implementers guidance on hiding discrepancies across systems and creating the illusion of a single repository for users. It also includes three sample frameworks—implemented using J2SE with JMS, J2EE, and Microsoft .Net—that readers can use to learn how to implement a distributed database management system. IT and development groups and computer sciences/software engineering graduates will find this guide invaluable.
