Model Based Materialized View Evolution: A Review

AbstractMaterialized views evolve in order to meet the user's requirement in the dynamically changing data warehouse environment. Therefore, materialized view evolution approach focuses on choosing materialized views in the design process of data warehouses or maintaining a materialized view in response to data changes or to data sources changes and sometimes to monitor the DW quality under schema evolution. Although few researchers have addressed materialized view evolution problem for evolving an appropriate set of views. But, none of the surveys provides a classification of materialized view evolution approaches in order to identify their advantages and disadvantages. This survey tries to fill this gap. The present paper provides a review of model based materialized view evolution methods by identifying the three main dimensions namely; (i) Framework, (ii) Architecture and (iii) Model/Design Model, that are the basis in the classification of materialized view evolution methods. The goal of this paper is to provide a comparative study on model based materialized view evolution methods, by identifying respective potentials and limits
