Service Perspective
The Service Perspective contains information about the system functions that support business activities
and/or general support activities.
The architecture encourages the use of common solutions, designs, and services where applicable and can
be used to facilitate the re-use of common activities. By "common" it is meant that the capabilities
(services, components and designs) can be reused by multiple systems and that new capabilities can be
realized by connecting sets of network accessible services. As a result, new components and services are
developed only when necessary, and re-use takes the place of re-creation.
