The Oracle Reference Architecture (ORA) includes the concept of Technology Perspectives. Which statements are true concerning ORA and Technology Perspectives?
Correct Answer: A,C,D,E
Explanation/Reference:
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.
Incorrect answers:
B: A technology perspective do include a reference architecture. Practical guidance is found in the Practitioner Guides. However, a Practitioner Guide is not included in the technology perspective.
Note: Whereas the ORA Technology Perspective describes the "what", the Practitioner Guides provide pragmatic guidance on "how".
