Abstract

In spatial databases, traditional approach is to build separate indexing structures for spatial and non-spatial attributes. This article introduces a new coupled approach that combines a 3D spatial primary index and a fuzzy non-spatial secondary index. Based on tests with several types of queries on a meteorological data set, it is shown that our coupled structure reduces the number of iterations and the time consumed for querying compared with the traditional uncoupled one.
