Hello!

First, I want to reccomend the Fantasticthe article about distributed
applications:
http://msdn.microsoft.com/architecture/default.aspx?pull=/library/en-us/dnbda/html/BOAGag.asp

I am designing a distributed application with a presentation layer as a
windows forms (we think to switch to the web on the future), a Business Logic
as web services (which act more like a Data Access Logic Component) and a
Data access layer as the Microsoft data access application block. The
Business processes will take place both at the web services functions and the
Stored procedures.

And here are my questions:
1. Does this architecture is accurate?
2. Do I need to define the business entities within the web services only to
import them to the UI or to define them also in my presentation layer? Maybe
I need to do both using Interfaces?

Thanks in advance!!
