Caching for Multi-dimensional Data Mining Queries
... tables or query results improves the granularity of caching by caching only those parts of the database that are accessed frequently. Secondly, chunk based caching works even without query containment— query Q3 can be partially answered using Q1 and Q2 (Fig. 1). Finally, it is much more efficient to ...
