Hi all,

I am reading Larman's book (Applying UML & Patterns - 2nd addition) to prepare for IBM - 486 exam. I am not clear about the difference between
1. "Domain Layer" and "Business Infrastructure Layer"
2. "Technical Services Layer" & "Foundation Layer"
(ref: Larman's book page number 451)

Can any body tell me what exactly the difference is.. and how to decide which class/object/package/api will fall in which layer....


thnks in advance
Tausif
