Explanation

Explanation: Oracle AIA provides two blueprints for implementing an ABCS: Oracle Mediator and BPEL. BPEL is used when the ABCS must augment content, validate content, or both. In most situations, the ABCS must have a conversation with one or more participating applications to enrich the content. It may also have to handle state management. (not B) In this scenario, BPEL is the preferred technology. BPEL enables you to perform the tasks listed previously and also enables you to extend the connector. The Oracle Mediator blueprint can be applied in situations in which you do not need the ABCS to do additional enrichment and validation of the content. In this model, the ABCS are implemented as Mediator services. Note: The role of the ABCS (Application Business Connector Services) is to expose the business functions provided by the participating application in a representation that is agreeable to a service interface. Note 2: The ABCS can be implemented in two ways: * The first approach is to make complete use of components that are built using Oracle Fusion Middleware technologies to make up the ABCS. The service is implemented as a Mediator service or a BPEL process. * The second approach is to build the transformation services, to a large extent, as part of the participating application. This approach can be taken when the participating application's technology stack has the infrastructure to perform the transformations. However, a lightweight ABCS still must perform the translations related to cross-reference details. Application Integration Architecture Foundation Pack: Implementing ABCS
