Research on Event-based Incremental Update of Spatial-Temporal Database

This paper presents a method called Event-based Incremental Update of Spatial-Temporal Database. By studying the event-based incremental update of spatial-temporal database, proposed event-based incremental information model, including incremental information modeling and the description method of incremental information based on XML, established the overall framework of the incremental update, including: event queue, spatial-temporal database, 3 agencies, 2 rules, and described the process of its implementation.
