Perspective (also
referred to as
architectural
perspective)

checklists, tactics and guidelines to guide the process

of ensuring that a system exhibits a particular set of

consideration across a number of the system‘s

architectural views.‖

Physical Entity A Physical Entity is a discrete, identifiable part of the
physical environment that is of interest to the user for
the completion of her goal. Physical Entities can be
almost any object or environment; from humans or
animals to cars; from store or logistics chain items to
computers; from electronic appliances to closed or
open environments.

Reference
Architecture

A reference architecture is an architectural design

pattern that indicates how an abstract set of

mechanisms and relationships realises a

predetermined set of requirements. It captures the

essence of the architecture of a collection of systems.

The main purpose of a reference architecture is to

provide guidance for the development of architectures.

One or more reference architectures may be derived

from a common reference model, to address different

purposes/usages to which the Reference Model may be

targeted.

Reference Model ―A reference model is an abstract framework for
understanding significant relationships among the
entities of some environment. It enables the
development of specific reference or concrete
architectures using consistent standards or
specifications supporting that environment. A reference
model consists of a minimal set of unifying concepts,
axioms and relationships within a particular problem
domain, and is independent of specific standards,
technologies, implementations, or other concrete
details. A reference model may be used as a basis for
education and explaining standards to non-specialists.‖

Requirement ―A quantitative statement of business need that must be
met by a particular architecture or work package.‖
