Another helpful way to think about architecture is that it is a process
a process that bridges a set of requirements, and constraints of the realization of a system.
The realization of the system is the implementation of the system.
The architecture is the design of the architect that creates something that satisfies the user, and can be realized by engineers by using readily available materials.
Elegance is a factor in the architecture, that is generally appreciated by architects.
It is also understood by the people who use the architecture.
It is the same building but what patterns do you observe?
What pattern is central and where is it repeated?
