Decomposing spatial databases and applications

Proceedings 11th International Workshop on Database and Expert Systems Applications, 2002
Topological invariants of spatial databases can act as a basic structure to tackle relevant problems in the field. It turns out that the main concern in these problems is the manipulation of topological invariants by means of efficient algorithms. To this aim, we introduce the notion of boundary decomposition of a topological invariant and give a ...

Genericity in Spatial Databases

2000
In 1980, Chandra and Harel investigated, in the context of the relational database model, which queries are “reasonable”. They characterized this class of queries by means of the concept of genericity, which has since taken a central position in the theory of computable queries.
