MSCRM

I don’t know if this question is suitable for this forum, but I can give it a shot… If i read the architecture whitepaper, they say that Microsoft CRM had an 4 tier fysical architecture, and when I look at the MSCRM 1.2 SDK, there they say that MSCRM had an 3 tier architecture. What’s the catch ? (i’m a newbie)

Hi, It’s having 4 layers (Presentation, Application, Platform and Database layer).
