Indexing OLAP Data

چکیده

In this paper we discuss indexing methods for On-Line Analytical Processing (OLAP) databases. We start with a survey of existing indexing methods and discuss their advantages and shortcomings. We then propose extensions to conventional multidimensional indexing methods to make them more suitable for indexing OLAP data. We compare and contrast R-trees with bit-mapped indices which is the most popular choice for indexing OLAP data today.

Storage and Indexing of Relational OLAP Views with Mixed Categorical and Continuous Dimensions

Due to the widespread adoption of locationbased services and other spatial applications, data warehouses that store spatial information are becoming increasingly prevalent. Consequently, it is becoming important to extend the standard OLAP paradigm with features that support spatial analysis and aggregation. While traditional OLAP systems are limited to data characterized by strictly categorica...

RCUBE: Parallel Multi-Dimensional ROLAP Indexing

This paper addresses the query performance issue for Relational OLAP (ROLAP) datacubes. We present RCUBE, a distributed multi-dimensional ROLAP indexing scheme which is practical to implement, requires only a small communication volume, and is fully adapted to distributed disks. Our solution is efficient for spatial searches in high dimensions and scalable in terms of data sizes, dimensions, an...

Integrating Geo-spatial Data into Olap Systems Using a Set-based Quad-tree Representation

During the last few years, On-Line Analytical Processing (OLAP) has emerged as a valuable tool for the analysis, navigation and reporting of hierarchically organized data from data warehouses. It particularly gained popularity as a building block of modern decision-support systems. With the use of geographical information systems in conjunction with OLAP, the need for storing spatial data and p...
