: This paper presents a model of data for mobile objects. The model is represented by spatial-temporal classes with mobility aspects, and represents the route and the trajectories ...
A join index hierarchy method is proposed to handle the "goto's on disk" problem in objectoriented query processing. The method constructs a hierarchy of join indic...
Modern database applications show a growing demand for efficient and dynamic management of intervals, particularly for temporal and spatial data or for constraint handling. Common...
Probabilistic data have recently become popular in applications such as scientific and geospatial databases. For images and other spatial datasets, probabilistic values can capture...
Search operations in databases require some special support at the physical level. This is true for conventional databases as well as for spatial databases, where typical search o...
