Which statement best describes the relationship between the Oracle Reference Architecture
(ORA) and Service-Oriented Architecture (SOA)?
A.
ORAincludes many different technology perspectives (for example, BPM, BI) Including SOA.
The SOA perspective provides a view of ORA focused on the products and technology applicable
to SOA.
B.
ORA embraces service orientation as a core tenet to consistently and uniformly deal with the
complexity of a heterogeneous computing environment common to enterprise IT.
C.
ORA embraces SOA as a core tenet; therefore, adopting ORA means that SOAis adopted as
well.
D.
ORA is a reference architecture based on architecture principles and best practices. SOA is a
marketing term that has become widely and ambiguously used within the industry.
E.
SOAis an architectural approach that isproduct- and vendor-independent,ORA is essentially a
SOA implemented using Oracle products and technology.
Explanation:
ORA does have a special relationship with SOA. ORA embraces
service-orientation as a core tenet to improve agility, rationalize functions and data,
and promote reuse in an effective manner. The entire strategy of SOA is not core to
ORA (not C), but the concept of exposing data and functionality as interoperable SOA
Services is core to ORA.
ORA must provide interoperability across all Oracle products and must also
effectively deal with the heterogeneity that exists in IT environments. SOA Services
provide a clean, consistent approach to deal with both of these complexities. This is
the reason that ORA includes service orientation as a core tenet.Stated as an architecture principle, this becomes:
* The architecture embraces services as the primary mechanism for
interoperability and integration.
