Take advantage of the benefits of loosely coupled Web services:
Loosely coupled components can operate independently of each other with no problems. This is an excellent fit when designing Web services, where all components are not always available. Coupling generally refers to the act of joining two things together, such as the links in a chain. But in software development, coupling typically refers to the degree to which software components/modules depend upon each other. The degree to which components are linked defines whether they operate in a tightly coupled relationship or in a loosely coupled relationship. With tightly coupled components, each component and any auxiliary dependent objects must be present at execution time as well as compile time. On the other hand, loosely coupled components can operate independently from one another.
