This paper introduces the relevant concepts of multidimensional ,data model,data cube and on- line analysis processing (OLAP)technobgies;puts forward the data clustering method used for setting up the dimensionality of data cube,and categorizes and collects the historical data using this arithmetic, so as to get the dimensionality for easily conducting OLAP technology analysis.on the basis of the historical data of condenser system,with the vacuum variation condition of condenser system as the subject,the multidimensional data model based data cube is set up,and the analysis is conducted using OLAP.The result shows that,to excavate the information from the data using OLAP is feasible,and is superior to the traditional data analysis method.
