Time Calculation Hierarchies, MDX, and DAX

We are in the midst of change in the world of Microsoft Business intelligence. The familiar SQL Server Analysis Services multidimensional model has been supplemented with the new tabular model. Alongside of the multidimensional MDX language we have the tabular DAX language.

This past year I have heard several excellent presentations at conferences showing the benefits of the tabular model and DAX. But I've decided to continue my focus on the multidimensional model and MDX.
