Index filtering and view materialization in ROLAP environment
2001
Proceedings of the tenth international conference on Information and knowledge management - CIKM'01
Using materialized view to accelerate OLAP queries is one of the most common methods used in ROLAP systems. However, high storage and computation cost make this method very difficult to be implemented in the actual environment. Among various issues associated with this, index selection and view materialization are two of the top challenges. In this paper, we propose to build indexes on subsets of the primary keys rather than the full sets if the index selectivity for these smaller indexes can
