Title: Issues in Spatio-temporal Database Systems: Data Models, Languages and Moving Objects
Issue Date: 2002
Abstract: Spatio-temporal is a broad designation that may refer to a wide variety of systemsdealing with the temporal evolution of spatial phenomena. Space and time are deeplyingrained in our commonsense reasoning patterns, and we have developed effectiveways of taking their properties into account to manage their intrinsic complexity. It istherefore no surprise that representing and managing data where the temporal andspatial aspects are fundamental is a hard task. There are numerous application domainsmotivating the developments in this area. The problems posed by the integration ofspatial and temporal dimensions of data require new solutions from database management systems. One application area which is receiving considerable attentionconcerns moving objects, represented as points in the spatial dimensions.This article presents an overview of spatio-temporal database systems, describing themain features of spatio-temporal objects and proposing a classification of spatiotemporalsystems based on the properties of the represented objects. This classificationallows understanding the complexity of the dynamics that underlie the temporalevolution of spatial phenomena. A survey of some issues in the spatio-temporal domainis also presented. The focus is on data models and languages for spatio-temporaldatabase systems with moving object applications in mind. Open issues for futureresearch, in the light of the features described as useful to being handled by spatiotemporalsystems, are also identified.
