A New Range Query Algorithm for Universal B-trees

Original language description

In multi-dimensional databases the essential tool for accessing data is the range query (or window query). In this paper we introduce a new algorithm of processing range query in Universal B-tree (UB-tree), which is an index structure for searching in multi-dimensional databases. The new range query algorithm behaves efficiently, especially for high-dimensional databases.We explain the algorithm using a geometric model providing an intelligible insight into the problem. More specifically, the model exploits an interesting relation between the Z-curve and generalized quadtrees. We also present experimental results for the range query algorithm implementation
