The Oracle Reference Architecture (ORA) includes the central layers as well as Technology
Perspectives and Industry perspectives. Which statements best describe how these are related
within ORA?
A.
The Technology Perspectives are reference architectures incorporating specific technologies,
products, and standards.
B.
The Technology Perspectives provide a view of ORA focused on specific technologies, product
and standards.
C.
The Industry Perspectives are reference architectures for specificindustries, for example, Telco,
Pharma.
D.
The Industry Perspectives extend the central layers of ORA toincludeindustry-specific
capabilities, components, and so on.
E.
ORA is a collection of reference architectures, some based on technology (Technology
Perspectives), and some based on industry verticals (Industry Perspectives).
Explanation:
The core ORA material is extended via architecture perspectives. There are two
types
of perspectives: Technology and Industry(not E).
B:Technology perspectives extend the core material by adding the unique capabilities,
components, standards, and approaches that a specific technology strategy offers.
SOA, BPM, EPM/BI, and EDA are examples of perspectives for ORA.
Each technology strategy presents unique requirements to architecture that includes
specific capabilities, principles, components, technologies, standards, etc. Rather than
create another reference architecture for each strategy, ORA was designed to be
extensible to incorporate new computing strategies as they emerge in the industry
In order to present the reference architecture in the most effective manner, each new
technology strategy adds a perspective to ORA. This enables the reference architecture
to evolve holistically. New computing strategies extend the core material, providing
further insight and detail as needed.
A perspective extends the ORA core collateral by providing views, principles,
patterns, and guidelines that are significant to that technology domain yet cohesive
with the overall ORA.
Industry perspectives extend the core material by adding the business functions,
business processes, data entities, software capabilities and components that an
industry vertical requires. Retail, Financial, Telco, and Pharma are examples of
industry perspectives for ORA.
