Methodology Choice for Building Pivot Tables with PowerPivot

[mattxu2006]

I have a report with 4 data tables that I have included in the data model. There are a few other Reference tables to map the data tables together. The data tables are about 100 columns (in total) of data and another 25 Columns (in total) of logical and reference formulas.

What are the pros and cons of rebuilding the report with all the formulas in the data model rather than the worksheets?

questions that come to mind:
Will the report use less memory?
Will it calculate faster?

thanks a bunch

Assuming you are using measures and not calculated columns then power pivot will be faster for sure. How materially depends on the calc and type of data.

Can you improve your schema at all over not a better star schema?

Thanks for your feedback, gazpage.
This particular project is now going in another direction, so I won't be immediately applying your tips.
I will be looking deeper into the resource that you provided for future use.

thanks again.
