CHAPTER 12 
Configuring the Physical Architecture
on a de facto top-down approach to establishing the software functional architecture. 
However, configuring the physical architecture is essentially a bottom-up method-
ology. The manner by which the structural design is devised must account for the 
following basic tenets concerning the manner in which the software architecture is 
crafted:
1. 
Functional analysis attempts to resolve unknown information about the problem 
and solution in a methodical manner. Because it involves analysis of the prob-
lem and solution space it implies a top-down methodology by which a large, 
incomprehensible problem or situation is reduced to smaller, more coherent 
design challenges.
