Statement

Architectural $4+1$

View

i$.$

To show the system hardware and how software

components are distributed across the processors in

the EMS.

ii$.$

To provide a model of the system's behavior and help

users validate the architecture against their

requirements.

iii.

To show the key abstractions in the system as objects

or object classes.

iv$.$

To show how the software is decomposed for the

development of an EMS.

v

To show the dynamic composition of interacting

processes within the EMS during runtime.
