Data Source View is a very important feature that SSAS count
on. We have previously explained how to create one. In this article we will
explain how to do day-to-day tasks with it.
It is important here to note that that DSV's can be used to
enhance your physical data model and to repeat the fact that changes made to
DSV do not impact your underlying data sources.
My previous article, SQL Server Analysis Services - Creating Data Source Views,
is a definite prerequisite for this article.
