pessimism

Implementation and experiments, the query processing efficiency of the DBMS backend. However, the extent to which the extended optimizer can support efficient query processing remains to be quantified and this study is only possible with a more sophisticated SQL backend which has buffer management and a conventional optimization strategy.

Die Baukonstruktionen des Auf- und Ausbaues,, have proved to be an efficient spatial structure for non-zero sized objects. The major contribution of this chapter is the proposal of a new kd-tree structure called the skd-tree. The algorithms for inserting, updating and searching the skd-tree have been presented. The skd-tree provides two types

For the implementation of the skd-tree suggested in Section 4.4.3, the dynamic skd-tree has similar storage overhead, more efficient intersection search and for more effective containment search. For the static implementation of the skd-trees and the R-trees, the containment search of
