Entity Framework And MSBI Application

[sailusailaja703]

I am in the process of Designing BI Solution. I am going to use MicroSoft Business Intelligence and ADO.net Entity Framework (Latest version).

Questions:

1. Which way to go Code 1st or Model/Data Base 1st?
2. How Can Entity Framework additionally help me to build BI application with the Standard MSBI Tools?

Thanks,
Sailaja
