15. ¿Qué es la arquitectura
del software?

16. 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

17. 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

18. “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
