Data warehouses have captured the attention of practitioners and researchers alike. But the design and optimization of data warehouses remains an art rather than a science. This book presents the first comparative review of the state of the art and best current practice of data warehouses. It covers source and data integration, multidimensional aggregation, query optimization, update propagation, metadata management, quality assessment, and design optimization. Also, based on results of the European Data Warehouse Quality project, it offers a conceptual framework by which the architecture and quality of data warehouse efforts can be assessed and improved using enriched metadata management combined with advanced techniques from databases, business modeling, and artificial intelligence. For researchers and database professionals in academia and industry, the book offers an excellent introduction to the issues of quality and metadata usage in the context of data warehouses.

This book presents the refereed proceedings of the 8th International Conference on Advanced Information Systems Engineering, CAiSE '96, held in Herakleion, Crete, Greece, in May 1996.
The 30 revised full papers included in the book were selected from a total of some 100 submissions. The book is organised in sections on CASE environments, temporal and active database technologies, experience reports, interoperability in information systems, formal methods in system development, novel architectures, workflow management and distributed information systems, information modelling, object-oriented database design, and semantic links and abstraction.

This volume reviews mid-1980s research in the development of computer systems that employ advanced technology to meet the needs of an expanding user population, while remaining sensitive to human requirements. Contributions from researchers in such diverse areas as user interface technology through to controlled experimental evaluations of systems and human factors principles are included in this volume. Topics considered includes recommendations for dialogue design, views of organizations on human factors, graphical and multimedia human/computer interaction, perspectives for the future of interactive systems, and the design of languages for applications in teleconferencing, databases for videotex systems and office automation.
