Design and Implementation of a Scalable Parallel System for Multidimensional Analysis and OLAP

Multidimensional Analysis and On-Line Analytical Processing (OLAP) uses summary information that requires aggregate operations along one or more dimensions of numerical data values. Query processing for these applications require different views of data for decision support. The Data Cube operator provides multi-dimensional aggregates, used to calculate and store summary information on a number of dimensions. The multi-dimensionality of the underlying problem can be represented both in relational and multi-dimensional databases, the latter being a better fit when query performance is the criteria for judgment. Relational databases are scalable in size and efforts are on to make their performance acceptable. On the other hand multi-dimensional databases perform well for such queries, although they are not very scalable. Parallel computing is necessary to address the scalability and performance issues for these data sets. In this paper we present a parallel and scalable infrastructure f...
