Spatio-temporal databases deal with geometries changing over time. The goal of our work is
to provide a DBMS data model and query language capable of handling such time …

We consider spatio-temporal databases supporting spatial objects with continuously
changing position and extent, termed moving objects databases. We formally define a data …

Even with much activity over the past decade, including organized efforts on both sides of
the Atlantic, the representation of both space and time in digital databases is still problematic …

Moving object databases are becoming more popular due to the increasing number of
application domains that deal with moving entities and need to pose queries. So far …

Investigates temporal changes of topological relationships and thereby integrates two
important research areas: first, 2D topological relationships that have been investigated …

Integrating spatio-temporal data as abstract data types into already existing data models is a
promising approach to creating spatio-temporal query languages. In this context, an …

Recently there is much interest in moving objects databases, and data models and query
languages have been proposed offering data types such as moving point and moving region …

Location-based services (l-services for short) comprise an emerging application involving
spatiotemporal databases. In this paper, we discuss this type of application in terms of …

An SQL extension is formalized for the management of spatio-temporal data, ie of spatial
data that evolves with respect to time. The extension is dedicated to applications such as …

Our world is changing at an increasing pace causing the validity intervals of information to
shrink. Therefore, the change of information becomes important information itself-an …
