This paper researches into the characteristic of aggregate query rewriting and gives a kind of rapidly approximate query computing model based on aggregate query rewriting under the data warehouse. The approximate query computing model is applied into a population statistic information system so that it achieves effective approximate answers. For realizing the quick and efficient answer to statistic data query, the approximate query computing model can be applied into these fields.
