Usually developers like having full control over their reports but what happens if you have someone designated to build reports who does not quite know the backend schema. A good way to separate the building of the data for the report and the report design could be stored procedures. Now I consume stored procedures using Oracle which is not much different consuming stored procedures with SQL Server, however building the procedures is much different between the two.

The dynamic management views (DMVs) in SQL Server 2005 are designed to give you a window into what's going on inside SQL Server.

In this article, we will begin an extended examination of the MDX surrounding drilling up and down within our Analysis Services cubes. Comprising an analytical technique by which an information consumer can maneuver between summarized ("drilling up") and detailed ("drilling down") levels of data, drilling up or down occurs along the lines of drilling paths that are defined within the physical structures of our cubes. Often specified by the cube's dimensional hierarchies, these paths can also be based upon alternative relationships that exist within or between dimensions.
