Web-enabled Data Warehouse

In this paper we review the basic architecture of a Web-enabled data warehouse. Industrial practices and valuable Web sites developed by leading vendors on the topic are provided. The usage of information usually follows the 80/20 rule, e.g., 80% of usage involves only 20% of resources and 80% of queries are requested by 20% of users. This phenomenon is also reported frequently in Web-enabled data warehouse. To enrich the literature, we propose an 80/20-based methodology to build such a Web-enabled data warehouse.
