Abstract

In this study, first, it is pointed out that R*-tree can be applied to OLAP (On-Line Analytical Processing) application. And then, some features of OLAP databases are introduced. After we present that how the R*-tree is applied to OLAP field, we also introduce how to enhance the R*-tree to further improve the search performance in accordance with the features of OLAP application. This study is focused on ROLAP (Relational OLAP), one popular kind of the OLAP systems. Our proposals are discussed in details and examined by experiments using synthetic data. The experimental result indicates that our proposals can clearly improve the search performance.
