Question # 14

Which of the following statements is false? Select the correct answer.

A.

Increasing the quantity of data model transformation logic within a service composition results in an increase in the development effort required to build the service composition due to an increase in the necessary data model mapping logic.

B.

Increasing the quantity of data model transformation logic within a service composition results in a decrease in the development effort required to build the service composition due to the fact that the intrinsic data model mapping logic residing within services can be leveraged.

C.

Increasing the quantity of data model transformation logic within a service composition results in a decrease in the performance of the service composition due to the need to execute the data model mapping logic at runtime.

D.

Increasing the quantity of data model transformation logic within a service composition results in an increase in the architectural complexity of the service composition due to the incorporation of the additional data model transformation layers.
