Benchmark Queries for Temporal Databases

This paper is intended to facilitate the development and evaluation of temporal database models by presenting semantic benchmarks with a large time component. It presents several temporal queries drawn from three application areas, and the results of some of these queries on the example relation instances. The schemas used in this paper are not based on any particular model but can be translated into most of the available temporal data models. With this in mind, it is our hope that other researchers will be able to use some of these queries as benchmarks to test their models and also as a basis for comparing di erent language proposals.
