In reading the book, I was impressed by how much the field of data warehousing has
advanced and matured. The book describes different aspects of data warehousing
technology and gives an insight into important research, technological, and practical
problems and solutions related to the data warehousing technology. The content of
the book covers fundamental aspects of data warehousing technology such as the
conceptual modeling and design of data warehouse systems, data warehouse refreshment,
query optimization, indexes, integration of the data warehouse technology
with data mining techniques, and, finally, new trends in data warehousing such as
temporal semistructured data models and spatial online analytical processing.
I am pleased to recommend this book to the readers. If you are a researcher, a data
warehouse developer, or just a keen reader wishing to understand important aspects
of data warehouses and their potential, you will find that this book provides both
a solid technical background and state-of-the-art knowledge on this interesting
and important topic. The book is a valuable source of information for academics
and practitioners who are interested in learning the key ideas in the field of data
warehousing. This book is likely to become a standard reference in the field of data
warehousing for many years.
