It also
sponsors the three technological layers shown above: operating system, middleware elements,
and platform elements. The concept insurance claims processor, which is part of the architectural
concept layer, generalizes the insurance claim Web services platform that is a part of the technological
environment. In the same fashion, the insurance claims hub is the architectural abstraction
created to describe data transformation and message dispatching functionalities (components of
the technological environment), which are part of an SOA intermediary product (appearing one
level below).

ARCHITECTURAL CONCEPTS AS MACHINES

His filed ???Z1???8 patent depicted the first mechanical computer, which contained the elementary
ingredients of modern machines. The driving concept advocated the separation of the two major
machine parts: storage and control.
