An Architectural Framework for Constructing Materialized Views in a Data Warehouse

T. V. Vijay Kumar and Kalyani Devi

Abstract— Data warehouse stores data accumulated over a period of time from disparate data sources for providing answers to analytical queries. These queries, which are long and complex in nature, have high query response time when processed against a large data warehouse. This response time can be reduced by constructing materialized views and storing them in a data warehouse. These views need to contain relevant and required information for answering future queries, so that future queries can be answered in a reduced response time to make decision making more efficient. A Materialized Views Construction Framework (MVCF), presented in this paper, lays down a strategy for constructing materialized views from previously posed queries on the data warehouse. The objective of MVCF is to enable construction of materialized views that are subject-specific and contain frequently accessed information that are capable of providing answers to future queries. This in turn would facilitate decision making.

Index Terms— Data warehouse, materialized view.
