Data transformation and manipulation of service response

One of the benefits of a SOA architecture is reusability of services. This means that services designed for one purpose can be reused for other different purposes.

At the same time, HR might use this same service to perform HR-related activities on the sales representatives records.

In the preceding example, if the service originally designed to supply data to the prospect customers portlet can also be used by the HR portlet, then the company can save valuable resources by reusing this service.
