Spatio-Temporal Databases

The textbook "Spatio-Temporal Databases" provides a comprehensive introduction to innovative query processing techniques specifically developed for large spatio-temporal databases of moving objects. It addresses complex movement pattern queries that offer high flexibility and expressiveness through the integration of variables and movement patterns. The content begins with the definition of flexible pattern queries and progresses to a detailed analysis of the Spatio-Temporal Pattern System (STPS) and density-based pattern queries. These systems are designed to manage millions of records containing information about mobile phone calls and are structured around cell towers and points of interest. The book also presents various evaluation algorithms aimed at identifying groups of trajectories that move together in space and time. Finally, a generic framework called DivDB is described, which aims to diversify query results and demonstrate the efficiency and effectiveness of the proposed queries. This comprehensive analysis and experimental evaluation make the book a valuable resource for professionals and researchers in the field of data processing.
