Transactional Information Systems book cover

Transactional Information Systems

Theory, Algorithms, and the Practice of Concurrency Control and Recovery

Transactional Information Systems is the long-awaited, comprehensive work from leading scientists in the transaction processing field. Weikum and Vossen begin with a broad look at the role of transactional technology in today's economic and scientific endeavors, then delve into critical issues faced by all practitioners, presenting today's most effective techniques for controlling concurrent access by multiple clients, recovering from system failures, and coordinating distributed transactions.

The authors emphasize formal models that are easily applied across fields, that promise to remain valid as current technologies evolve, and that lend themselves to generalization and extension in the development of new classes of network-centric, functionally rich applications. This book's purpose and achievement is the presentation of the foundations of transactional systems as well as the practical aspects of the field what will help you meet today's challenges.

Reviews

  • "This book is a major advance for transaction processing. It gives an in-depth presentation of both the theoretical and practical aspects of the field, and is the first to present our new understanding of multi-level (object model) transaction processing. It's likely to become the standard reference in our field for many years to come."
