Temporal Objects for Spatio-Temporal Data Models and a Comparison of Their Representations

The authors have presented a new model for temporal objects and temporal databases that, in particular, offers quite different modeling options for spatio-temporal databases. The investigation of the relative expressiveness of the different models gives a clear picture of the relationships between these models. In particular, it can be seen that, compared with the traditional (flat) view of temporal databases, the ADT approach is more versatile and offers much more control over temporal behavior, even for linearly constrained objects.
