An Enterprise
Architecture represents the fundamental description
of an organisation, its structure, the information
that it requires, the business processes that
use and produce the information, its software
applications that provide the services the
business processes depend on, the structure
of the application components, products, their
interrelationships to each other and the technical
infrastructure and environment in which they
operate, all driven by the principles, standards,
etc. that govern their design and evolution
over time.
