The software architecture of a program or computing system is the structure or structures of the system, which comprise software elements, the externally visible properties of those elements, and the relationships among them.
Externally visible properties are what assumption other elements can make of an element
SA intentionally abstracts away internal properties of elements (to better encounter complexity)
In construction, there are blueprints of
Each of these views specifies a single entity (i.e. the construction) from a different perspective (used by a different person, for a different goal).
Similarly there are different structures and views in SA.
A popular software myth: first we build a software that satisfies functional requirements, then we will add or inject non-functional requirements to it.
