Typical Service Consumers

© SAP 2007 / Page 23

User Interfaces as Service Consumers:

Offering easy ways to call service functionalities

Creation of role, task, or process specific

user interfaces

Creation of reusable user interfaces for service calls

Services as Service Consumers:

Offering of web services that use other web services to provide functionality

Compound services combine functionalities of several services to one service

Tailor services to specific needs: Services offer tailored interfaces to provide

easier or special possibilities to call the original service functionality

Composite Applications as Service Consumers:

Using services within an application context

Calling services with process context specific information

Combining functionalities of different services to a complete application
