【Abstract】Based on the historical data, what-if analysis can analyze the hypothetical scenarios and provide useful information for the decision-maker. Aiming at the problem of re-computation of data cubes in what-if analysis, this paper presents an algorithm of incremental computation of data cube for Max function to reduce the access time of fact table. Experimental results show that the performance of incremental computation can be improved about 15%.
