“the process of defining the architecture, components, interfaces, and other characteristics of a system component” and “the result of [that] process.”
“There are two ways of constructing a software design. One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are obviously no deficiencies. The first method is far more difficult.”
The software architecture of a program or computing system is the structure or structures of the system, which comprise software components, the externally visible properties of those components, and the relationships among them.
Marry your architecture in haste, repent at your leisure.
