A Data Warehouse (DW) can be seen as a set of materialized views defined over the source relations. During the initial design and evolution of a DW, the DW designer is faced, on many occasions, with the problem of selecting views to materialize in the DW. This study presents the critical survey of the methodologies to select materialized view in more efficient way. In this study, we are summarizing all these methodologies with critical analysis. Advanced solutions are particularly focusing the evolutionary optimization methods. I have analyzed and compartmentalized the available literature on the basis of relevant evaluation parameters. Important books, PhD thesis, links, etc. are also given in study. To work out this study studied more than fifty research papers. This study may be helpful to the researchers, who are working in the domain of the Data Warehouse focusing on the view selection problem. |
