内容説明 A summary of research carried out in the CHOROCHRONOS Project， established as an EC-funded Training and Mobility Research Network with the objective of studying the design， implementation， and application of spatio-temporal database management systems. The nine coherent chapters by leading research groups are written in a tutorial style， making the research contributions of the project accessible to a wider audience interested in spatio-temporal information processing. Following an introductory overview， the book presents chapters on ontologies for spatio-temporal databases， conceptual models， spatio-temporal models and languages， access methods and query processing， architectures and implementation of spatio-temporal DBMS， interactive spatio-temporal documents， and future perspectives.
