Antes de proseguir ... yo uso el lenguaje que

más me conviene y punto.

¿Qué es la arquitectura del software?

1. “A formal description of a system, or a detailed plan of the system at component level to guide its

implementation.”

The Open Group Architecture Framework

2. “The structure of components, their inter-relationships, and the principles and guidelines governing their design and evolution over time.”

The Open Group Architecture Framework

“In most successful software projects, the expert developers working on that project have a shared

understanding of the system design. This shared understanding is called “architecture.” This understanding

includes how the system is divided into components and how the components interact through interfaces. These components

are usually composed of smaller components, but the architecture only includes the components and

interfaces that are understood by all the developers ... Architecture is about the important stuff. Whatever that

is.”

Martin Fowler
