Abstract

This paper contributes a general approach to characterizing patterns of change in a spatio-temporal database.While there is a particular interest in modelling and querying how spatio-temporal entities evolve, the approach contributed by the paper is distinctive in being applicable without modification to aspatial entities as well. The paper uses the Tripod spatio-temporal model to describe and instantiate in detail the contributed approach. After briefly describing a typical application and providing basic knowledge about Tripod, the paper characterizes and classifies evolution queries and describes in detail how they are evaluated.
