Implementing the Data Transfer Object Pattern
The previous two chapters discussed mechanisms for optimizing a client’s use of a Web Service. You will find that, in practice, Web Service operations are relatively expensive when compared to a local method call between objects in the same process. Consider Figure 16–1 (previously shown as Figure 4–2). A communication path between two components, ArchitectureAComponent and ArchitectureBComponent, contains at least two transformations in a single direction and an intermediate format. Then, consider that each call must return from the one-way trip with a new value.
