Which statements are true concerning ORA and Technology Perspectives?

The Oracle Reference Architecture (ORA) includes the concept of Technology Perspectives.
Which statements are true concerning ORA and Technology Perspectives?

A.
Each Technology Perspective focuses on a particular set of products and technology.

B.
A Technology Perspectiveincludesboth reference architecture views as well as practical
guidance and approaches for successfully implementing the changes required to embrace the
products and technology.

C.
The Technology Perspectives can be used individually or in combinations, for example, SOA
with BI.

D.
The Technology Perspectives can be used individually or in combinations. When used in
combinations, the SOA Technology Perspective must be included.

E.
Each Technology Perspective is part of ORA and is part of an Enterprise Technology Strategy;
i.e. a Technology Perspective is the connection between ORA and an Enterprise Technology.

Explanation:
Technology perspectives extend the core material by adding the unique capabilities,
components, standards, and approaches that a specific technology strategy offers.(A)
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.
