An Algebra for Online Analytical Processing Data Cube

D. Yang

Abstract

Data cube is the central mechanism in multidimension database and online analytical processing (OLAP) based on multidimensional analysis. In this paper, an algebra for OLAP data cube is proposed, which supports multidimensional database and analysis. It can be the theoretical foundation of semantic specification of data warehousing and OLAP manipulations. Some applications of the new mathematical tool are presented as well to show the power of the contribution.
