E-commerce is a growing and vital part of today's new economy. At the heart of e-commerce, not to mention traditional data-intensive business, is transaction processing. Transaction processing includes the highly complex processes that transfer money from one account to another, reserve seats on a flight, control stock trading and make adjustments to inventory - just to give a few examples.
Written by two widely recognized authorities, Fundamentals of Transactional Information Systems approaches the subject from the bottom up, focusing on the low-level algorithms out of which various pieces of transaction processing are constructed. It also examines higher-level challenges such as concurrency (synchronizing data stored in multiple locations) and recovery (protection against system failures). This is indispensable knowledge for an ever growing audience of programmers and database architects working on business systems of all kinds.
Authoritative coverage from star researchers - both big names in the transaction processing field A topic of increasing importance to developers working for both traditional and e-commerce companies

This book changes that by going far beyond transaction processing. It starts with the same fundamentals as the older book, and even covers many of the same topics, such as concurrency control, but it addresses each topic from a much wider perspective. For example, the discussion of concurrency goes far beyond the issues of transaction processing as a middleware component. It extends into application, database and search issues. Another indication that this book is more up-to-date is the material on queue managers. While they are at the opposite end of the spectrum from transaction processing monitors, they are integral to any discussion of transactional information systems. More importantly, both transaction processing monitors and queue managers are used in modern enterprise architectures. Having both topics discussed in great detail is a major point in this book's favor.
Personally I intend to keep my copy of the older "Transaction Processing: Concepts and Techniques" because it does cover some of the subject matter more deeply. However, this book has replaced it as my principal reference and if I had to choose between them this is the one I'd go with.
