Towards a model for spatio-temporal schema selection

Schema versioning provides a mechanism for handling change in the structure of database systems and has been investigated widely, both in the context of static and temporal databases. With the growing interest in spatial and spatio-temporal data as well as the mechanisms for holding such data, the spatial context within which data is formatted also becomes an issue. This paper presents a generalised model that accommodates schema versioning within static, temporal, spatial and spatio-temporal relational and object-oriented databases.
