Searching in high-dimensional spaces: Index structures for improving the performance of multimedia databases

Christian Böhm, Stefan Berchtold, Daniel A. Keim
2001 ACM Computing Surveys

XZ-Ordering: A Space-Filling Curve for Objects with Spatial Extension [chapter]

Christian BÖxhm, Gerald Klump, Hans-Peter Kriegel
1999 Lecture Notes in Computer Science  
In this paper, we point out that neither a hybrid solution using relational databases and a separate spatial index nor the approach of existing object-relational database systems provide a satisfying solution  ...  This robustness is achieved by avoiding object duplication, allowing overlapping Z-elements, by a novel coding scheme for the Z-elements and an optimized algorithm for query processing.  ...  In this experiment, we stored 81,000 polygons in the database and retrieved 1% of them in window queries. Z-Ordering has a clear minimum at a resolution of g = 8 with a satisfying query performance.  ...
