Interest Centers to Improve the Maintenance Load of Materialized Views in Real-Time Data Warehouse

In this paper, the authors have developed an approach to specify when updating materialized views in real-time data warehouse. The paper is to improve the maintenance load which may have a bad impact on the query response time especially in a real-time environment where the data updates are frequent and the freshness of served data is highly required. They have introduced a new concept "Interest center" which is a frequent set of user queries i.e. common and frequent user demands. They identify the interest centers from the historic of user queries.
