Bitmap index based on dimension hierarchical encoding in data warehouse

Hu Kongfa~(1,2) Dong Yisheng~2 Chen Ling~1(~1 Department of Computer Science and Engineering, Yangzhou University, Yangzhou 225009, China)(~2Department of Computer Science and Engineering, Southeast University, Nanjing 210096, China)  
The OLAP (on-line analytical processing) query rapidity was improved by reducing multi-table join, compressing the dimension attribute join keys and effectively aggregating the query data in OLAP. In this paper to build dimension hierarchical encoding surrogate key for each dimension member by using the dimension hierarchical characteristic is proposed. By using the small dimension hierarchical encoding and their hierarchical prefix path, this method can rapidly retrieve the matching dimension hierarchical encoding and evaluate the set of query ranges for each dimension. As a result, this method can drastically reduce the multi-table join effort and so much as could remove completely one or more join operations, reduce the disk I/Os, and highly improve the efficiency of OLAP queries.
