Service composition is the creating of a new SOA Service by aggregating existing SOA Services. Which statements are correct concerning the use of service composition within the Service-Oriented Integration architecture?
Correct Answer: C
Explanation/Reference:
Service composition is the ability to leverage lower-level services to create a higher-level service When doing composition, the developer should respect the layering of the architecture. Thus, a Business Service could leverage existing Connectivity Services or Data Services and a Data Service could leverage existing Connectivity Services. But, a Data Service should not call a Business Service and a Connectivity Service should not call a Data Service or a Business Service Reference: Oracle Reference Architecture, Service-Oriented Integration, Release 3.0
