Question 5

OASIS s SOA-RM defines high-level terms intended to provide commonality when discussing and describing SOA. Which two statements are true when comparing SOA-RM with Oracle's Service meta-model?

Select all that apply, then click Submit answer.

○
Both SOA-RM and Oracle's Service meta-model separates the textual aspects from the technical aspects.
○
SOA-RM and Oracle's Service meta-model differ on the specifics of the constituent parts of a Service.
○
Oracle's Service meta-model breaks out the service interface as a first class facet of a Service; whereas the SOA-RM combines the service interface in with the service description.
○
SOA-RM addresses Usage Agreements as defined by Oracle.
○
SOA-RM execution context maps directly with Oracle's definition of a Service Implementation.

Reference / correct answer:

Both SOA-RM and Oracle's Service meta-model separates the textual aspects from the technical aspects.

Oracle's Service meta-model breaks out the service interface as a first class facet of a Service; whereas the SOA-RM combines the service interface in with the service description.

The SOA RM definition of a Service is similar to the one provided by ORA. There is no glaring discrepancy between the two concerning the definition of a Service. However, the two differ on the specifics of the constituent parts of a Service. The SOA RM describes three constituent parts of a Service just like ORA does. ORA breaks out the Service Interface as a first class facet of a Service; whereas the SOA RM lumps the service interface in with the service description.

ORA separate the human-readable, textual aspects of the Service from the technical aspects. The textual aspects are the Usage Agreement and the Service Contract. The technical aspects are the Service Interface and the Service Implementation. The SOA RM does not separate them. Both the service description and the contracts and policies include both technical and textual contents.

Select an option, then click Submit answer.

○

○
This will provide the greatest opportunity for re-use from the widest possible number of consumers.
○

○
Document-style interfaces tend to be quite fine-grained so that they can be re-composed in innovative ways.
○
