Advanced Signature Indexing for Multimedia and Web Applications presents the latest research developments in signature-based indexing and query processing, specifically in multimedia and Web domains. These domains now demand a different designation of hashing information in bit-strings (i.e., signatures), and new indexes and query processing methods. The book provides solutions to these issues and addresses the resulting requirements, which are not adequately handled by existing approaches. Examples of these applications include: searching for similar images, representing...

Infrastructures have become more and more critical to the functioning of society, as economic and social processes to a large extent rely on the services provided by such systems. Failure of these infrastructures, therefore, is one of the most important vulnerabilities of modern society. In addition and simultaneously much change is taking place within and around these infrastructures. This change includes: increasingly rapid technological change, rapid institutional change, increasing system complexity, increasing trans-boundary dependencies, tensions between market concerns addressing...

This book develops a theory for transactions that provides practical solutions for system developers, focusing on the interface between the user and the database that executes transactions. Atomic transactions are a useful abstraction for programming concurrent and distributed data processing systems. Presents many important algorithms which provide maximum concurrency for transaction processing without sacrificing data integrity. The authors include a well-developed data processing case study to help readers understand transaction processing algorithms more clearly. The book offers...

The chapters of this book provide an excellent snapshot of current research and development activities in the area of query processing and optimization. They supply potential answers to many questions that have been raised for new types of database systems and at the same time reflect the variety of the different approaches taken. The book acts both as a reference for the state of the art in query processing for the -next generation- of database systems, and as a good starting point for anybody interested in understanding the challenging questions in the area. Furthermore, the book will...

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...

Protect your digital resources This book addresses critical issues of preservation, giving you everything you need to effectively protect your resources-from dealing with obsolescence, to responsibilities, methods of preservation, cost, and metadata formats. It also gives examples of numerous national and international institutions that provide frameworks for digital libraries and archives. A long-overdue text for anyone involved in the preservation of digital information, this book is critical in understanding today's methods and practices, intellectual discourse, and preservation...

Significantly updated and expanded, this second edition offers a far more comprehensive and sophisticated treatment of the subject area than can be found in other sources. It revisits the subject of cataloging and analyzes it in the context of today's digital environment, providing a fascinating examination of the components that are crucial for successful and effective subject retrieval in online public access catalogs. From language issues to problems of indexing and classification, this book guides you through the theoretical and practical frameworks of information storage and retrieval...

Search engines, subject gateways, descriptive metadata, Web cataloging--everyone is looking for ways to support information discovery and retrieval on the Internet. To become full partners in new digital access ventures, library and information professionals need to be familar with effective tools and stategies, and need to make decisions about what is appropriate for different resources, settings and communities. This book takes a look at what has been done in providing subject access to networked resources, and what is around the corner.
