| Abstract: | The size of the materialized views of a data-cube enlarges with the increase of the data amount,the dimensionality and the complicacy of the dimension hierarchy of the data-cube in data warehouse and,therefore,results in data explosion.To solve this problem,compressing technologies for data-cube emerge and become a significant branch of data-cube technologies.This article introduces the content of OLAP and data cube,proposes and analyzes the data cube compression algorithm for the various representatives,an... |
