I never thought that I'll do a commercial to Microsoft, but
Project Real is a great thing that they did and they should get the credit for it. This project is a full end-to-end BI solution, including ETLs (using SSIS), Analysis Services cubes and mining modules, Reporting Services reports, end-user Panorama views and more.
We work with Panorama as our main GUI tool to show our users the cube's data as tables, charts, dashboards, etc, so this project is really helping us to learn how to implement our project from the first ETL step all the way to the last Panorama step.
