A review of the evolution of spatio-temporal data types

Abstract

The motivation for this presentation is to show current approaches for modelling processes in time and space. Different approaches have taken place to extend existing RDBMS to spatio-temporal functionality. The re-examination of the relational model and the demand for spatial as well as temporal data types has driven the effort to create new types of databases. The capabilities of the spatial and temporal object database Tripod which is based on a spatio-temporal data type approach is the foundation for this study (Griffiths et al. 2001). A review of the moving-object model is made (Gueting et al. 2003) and its relation to the implemented Tripod data model is outlined, following the evolution on their common roots.
