Question 3: Service A is an entity service with a functional context dedicated to invoice-related processing. Service
B is a utility service that provides generic data access to a database.
In this service composition architecture, Service Consumer A sends a SOAP message containing an
invoice XML document to Service A (1). Service A then sends the invoice XML document to Service B (2),
which then writes the invoice document to a database.
The data model used by Service Consumer A to represent the invoice document is based on XML
Schema A. The service contract of Service A is designed to accept invoice documents based on XML
Schema B. The service contract for Service B is designed to accept invoice documents based on XML
Schema A. The database to which Service B needs to write the invoice record only accepts entire
business documents in Comma Separated Value (CSV) format.
Due to the incompatibility of XML schemas used by the services, the sending of the invoice document
from Service Consumer A through to Service B cannot be accomplished using the services as they
currently exist. Assuming that the Contract Centralization and Logic Centralization patterns are being
applied, what steps can be taken to enable the sending of the invoice document from Service Consumer A
to the database without adding logic that will increase the runtime performance of the service
composition?
A.The Data Model Transformation pattern can be applied so that the invoice document sent by Service
Consumer A is transformed into an invoice document that is compliant with the XML Schema B used by
Service A. The Data Model Transformation pattern can be applied again to ensure that the invoice
document sent by Service A is compliant with XML Schema A used by Service B.
B.The service composition can be redesigned so that Service Consumer A sends the invoice document
directly to Service B. Because Service Consumer A and Service B use XML Schema A, the need for
transformation logic is avoided. This naturally applies the Service Loose Coupling principle because
Service Consumer A is not required to send the invoice document in a format that is compliant with the
database used by Service B.
C.The Standardized Service Contract principle can be applied to the service contract of Service A so that
it is redesigned to use XML Schema A. This would make it capable of receiving the invoice document from
Service Consumer A and sending the invoice document to Service B without the need to further apply the
Data Model Transformation pattern.
D.None of the above.
Correct Answer:C
