Service Method

When a service is implemented as a component, the functions or capabilities it exposes via the component's technical interface are referred to as methods, a term that was popularized by object-orientation and component-based design approaches.

Because a component can be designed in accordance with service-orientation principles or alternative design paradigms, the term service method is used to indicate that the method is part of an actual service (a component to which service-orientation has been applied).

Note that traditional object-oriented class notations can be used even when designing service-oriented classes, as explained in Chapter 14 of "SOA: Principles of Service Design".
