What can you do when database performance doesn't meet expectations? Before you turn to expensive hardware upgrades to solve the problem, reach for this book. Refactoring SQL Applications provides a set of tested options for making code modifications to dramatically improve the way your database applications function. Backed by real-world examples, you'll find quick fixes for simple problems, in-depth answers for more complex situations, and complete solutions for applications with extensive problems. Learn to:

• Determine if and where you can expect...

Data mining from traditional relational databases as well as from non-traditional ones such as semi-structured data, Web data, and scientific databases housing biological, linguistic, and sensor data has recently become a popular way of discovering hidden knowledge.

This book on database support for data mining is developed to approaches exploiting the available database technology, declarative data mining, intelligent querying, and associated issues, such as optimization, indexing, query processing, languages, and constraints. Attention is also paid to the solution of data...

The semantic Web offers new opportunities for information processes. This book is devoted to the core issue of data integration at the semantic level and demonstrates the applicability of the techniques developed to spatio-temporal representation and reasoning and geographic information systems.

Preceded by a motivating introduction and an overview of the state of the art in the field of information integration, fundamental problems of terminological representation, terminological reasoning, and semantic translation are treated in detail. The theoretical results and techniques developed...

Business-to-business (B2B) integration is a buzzword which has been used a lot in recent years, with a variety of meanings. Starting with a clear technical definition of this term and its relation to topics like A2A (Application-to-Application), ASP (Application Service Provider), A2A, and B2C (Business-to-Consumer), Christoph Bussler outlines a complete and consistent B2B integration architecture based on a coherent conceptual model. He shows that B2B integration not only requires the exchange of business events between distributed trading partners across networks like the Internet, but...

Ein Datenbanksystem ist die zentrale Softwarekomponente der meisten betrieblichen Anwendungssysteme und gehort zur Basissoftware aller Arbeitsplatzrechner.

Dieses Lehrbuch bietet daher eine anwendungsorientierte Einfuhrung in die Datenmodellierung und Datenbanktechnologie unter besonderer Berucksichtigung der Anforderungen von Unternehmen. Dank vieler Beispiele stellt das Buch auerst anschaulich im ersten Teil moderne Methoden und Techniken vor, mit denen ein redundanzfreies Unternehmensdatenmodell entwickelt werden kann, ausgehend von einer umfangreichen Anforderungserhebung und...

Spatio-Temporal Databases explores recent trends in flexible querying and reasoning about time- and space-related information in databases. It shows how flexible querying enhances standard querying expressiveness in many different ways, with the aim of facilitating extraction of relevant data and information. Flexible spatial and temporal reasoning denotes qualitative reasoning about dynamic changes in the spatial domain, characterized by imprecision or uncertainty (or both). Many of the contributions focus on GIS, while some others are more general, or focus on related...

This book constitutes the refereed proceedings of the 11th Annual International Conference on Research in Computational Molecular Biology, RECOMB 2007, held in Oakland, CA, USA in April 2007.

The 37 revised full papers address all current issues in algorithmic, theoretical, and experimental bioinformatics.

Together with volume VI of the Transactions on Rough Sets series, this book commemorates the life and work of Zdzislaw Pawlak (1926-2006). It presents papers that reflect the profound influence of a number of research initiatives by Professor Pawlak, introducing a number of advances in the foundations and applications of AI, engineering, logic, mathematics, and science, which have had significant implications in a number of research areas.

This book constitutes the refereed proceedings of the 5th RECOMB Comparative Genomics Satellite Workshop, RECOMB-CG 2007, held in San Diego, CA, USA, in September 2007. The 14 revised full papers presented address a broad variety of aspects and components of the field of comparative genomics, ranging from quantitative discoveries about genome structure to algorithms for comparative inference to theorems on the complexity of computational problems required for genome comparison.
