Working with consultants in developing the core DW model and haven't started the semantic layer yet, however, they indicated that they are more familiar (skilled) in creating physical tables from dimensional modeling (star schemas, extended star schemas, snowflakes, etc). Are there any good examples, courses, reading material, etc. where this practice can be transitioned to start creating views in lieu of physical tables in the data access layer of the warehouse? I understand in a few cases you may want to create aggregrate tables to satisfy requirements, but for the most part, this is a performance consideration. Any guidelines on taking this route as well? :-)
