Abstract
We examine the performance of B+-tree
based index structures for
multiple sets, as developed in the context of object bases. Index
structures for multiple sets can be classified into those that group
entries according to their key value and those that group entries
according to their set membership. The former are particularly suited
for exact match queries on all indexed sets, the latter especially
support range queries on a small number of all indexed sets. The goal
is to thoroughly evaluate the performance of both grouping strategies.
There exist two good reasons for adding a new index structure to the
evaluation:
- The performance potentials of set grouping index structures are
not yet fully exploited.
- Up to now, the database administrator has to choose between the
key grouping and the set grouping index structures. If the application
profile consists of both, exact match queries and range queries, this
is not really a choice. Hence, a more flexible index structure is
needed which can be tuned to a given mix containing both, exact
match and range queries.
These two reasons led us to the development of the CG-tree. The focus
of the paper is on introducing the CG-tree and on a thorough analysis
of the performance of the CH-index, H-tree, and CG-tree under various
conditions.
