When two or more technology perspectives are combined, which statement best describes how
the Oracle Reference Architecture (ORA) applies to the combination?
A.
One of the layersin ORAis the Business Services layer that contains the SOA Services. It is
these SOA Services that provide the connection between different technology perspectives;
therefore the Business Services layer is the interlock between two or more technology
perspectives.
B.
Each technology perspective adds to the core ORA capabilities. The core ORA capabilities
support each of the technology perspectives by providing a common foundation.
C.
The vertical layersin ORA (Enterprise Development, Enterprise Security. Enterprise
Management) provide the capabilities needed to combine two or more technology perspectives.
D.
Each technology perspective is a separate reference architecture that leverages ORA as the
common foundation for each of the individual reference architectures.
E.
The vertical layers of ORA are identical for each technology perspective. Each technology
perspective adds capabilities to the horizontal layers of ORA, especially the business Processes,
Business Services, and Information Assets layers.
Explanation:
The reference architecture is designed to support an expanding list of technology
strategies. It is also important that the various technology perspectives can be easily combined
since they are very much complementary.
Documenting how each technology perspective relates and combines with all the other
technology perspectives would be onerous and unwieldy. This is the reason that ORA
embraces service orientation at the core so that services provide a consistent
mechanism to expose and combine various technologies and the capabilities.
