When I was an employee at AT&T I was heavily involved in OLAP cubes and data warehouses.

I developed two OLAP cube courses that were put into AT&T University:

  1. Introduction to OLAP Cubes
  2. Excel Pivot Tables with OLAP Cubes

I did both in Camtasia and recorded them in the evenings when the noise levels where very low.

Both were well received.
