Service Oriented Architecture
►A
set of components which can be invoked, and
whose interface descriptions can be published and
discovered - W3C.
► The
policies, practices, frameworks that enable
application functionality to be provided and
consumed as sets of services published at a
granularity relevant to the service consumer.
