Moving Objects Databases

"This book represents a milestone in the synthesis of temporal and spatial database concepts and techniques. It unifies and organizes the existing research into a coherent whole and presents substantial new results and approaches in many areas. In each case it begins with what is known, then it introduces the new concepts in an abstract and general model, and then it translates the ideas into a pragmatic representation of data structures or SQL-like query language extensions. As such, the book makes both an excellent text and an excellent reference. It also takes you to the frontiers of our understanding, so it is a great point of departure for a new researcher who wants to advance this field." --from the foreword by Jim Gray, Microsoft Research
