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 paper presents the critical survey of the methodologies to select materialized view in more efficient way. In this paper, the authors are summarizing all these methodologies with critical analysis. Advanced solutions are particularly focusing the evolutionary optimization methods.
