Foreword

When I was asked to write the foreword of this book, I was both honored and enthusiastic about contributing to the first book covering the topic of spatial data warehousing. In spite of over ten years of scientific literature regardingspatial data warehousing, spatial data mining, spatial online analytical processing, and spatial datacubes, Malinowski and Zim´nyi are the first to invest a the energy necessary to provide a global view of spatial data warehousing in a coherent manner. This book introduces the reader to the basic concepts in an academic style that remains easy to read. Although one might think initially that there isnothing special about spatial data warehouses, this book shows the opposite by introducing fundamental extensions to the development of spatial data warehouses. On the one hand, there are extensions required for the design and implementation phases, and on the other hand there are extensions that improve the efficiency of these phases. This book offers a broad coverage of these extensions while at thesame time guiding the reader to more detailed papers, thanks to a representative bibliography giving a sample of the main papers in the field. In addition, this book contains a glossary that is very useful for the reader since the datacube paradigm (also called analytical or multidimensional database paradigm) is very different from the traditional database paradigm (also called transactional oroperational database paradigm). Of particular interest in this book is the coverage of spatial datacubes, of their structure, and of implementation details in a data warehouse perspective. In particular, the different types of spatial hierarchies, spatial measures, and spatial data implementations are of interest. As a technology of choice to exploit data warehouses, OLAP technology is discussed...
