A modular approach has been taken to document the Oracle Reference Architecture (ORA).
Select the statements that are true for this modular approach?
A.
The ORA library has a document dedicated to each Oracle product suite.
B.
ORA is a collection of reference architectures, some based on specific technologies
(Technology Perspectives), and some on industry verticals (Industry Perspectives).
C.
ORA is a single-reference architecture but is documented via different views of the architectssome focused on specific technologies (Technology Perspectives), and some on industry verticals
(Industry Perspectives).
D.
The number of Technology Perspectives and Industry Perspectives will increase over time.
E.
The technology Perspectives are complete, but the Industry Perspectives will increase over
time as more verticals are Included.
Explanation:
A: The scope of ITSO is all of Oracle’s product families. However, the Oracle
technology
real estate is extremely large and evolves as new products are introduced. Thus, the
ITSO material will continue to grow as more ORA documents are created, additional
ETSs are covered, and additional ESDs are created.
C, D: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. The perspective includes:
* A foundation document describing the terms, concepts, standards, principles, etc.
that are important to the ETS.
* An infrastructure document that defines a reference architecture built using the
technologies pertinent to the ETS.
An industry reference architecture is a set of high level architectural representations
which characterize the current state architecture of an enterprise and a desired state, or
architectural vision, based on the ORA.
