| Abstract: | Based on the MOLAP technology of multi-dimension array,the article proposes a new method of compressed store,which was stored in dimensions by binary code.The method can solve the lower efficient problem in aggregation query and dealing with the inner layer of the dimension for the common used multi-dimensions array linearization,which made use of compressed store. |
