Abstract
The dimension data or measurement data in data warehouse is determined,and the multi-dimensional analysis on it is also carried out based on the established data.In reality,due to the complexity and uncertainty of environment,the multi-dimensional analysis for fuzzy data is often needed.In this paper we achieve the fuzzification of determined data by using membership functions,generate the data cube based on the fuzzy data and conduct multi-dimensional analysis on it.
