7 ½ X 9 ¼ in The current trends in consumer electronics–including the use of GPS-equipped PDAs, phones, and vehicles, as well as the RFID-tag tracking and sensor networks–require the database support of a specific flavor of spatio-temporal databases. These we call Moving Objects Databases. Why do you need this book? With current systems, most data management professionals are not able to smoothly integrate spatio-temporal data from moving objects, making data from, say, the path of a hurricane very difficult to model, design, and query. Whether your field is geology, national security, urban planning, mobile computing, or almost anything in between, this book s concepts and techniques will help you solve the data management problems associated with this kind of data.
