Background documentation Back-End Connectivity Layer  Locate the document in its SAP Library structure

The back-end connectivity layer provides composite applications with transparency regarding implementation specifics of the services in the back end it communicates with. Web Services are the recommended technology for connecting composite applications to target, enterprise SOA-based back-end systems.

Back-end independency keeps the composite applications flexible and reduces the effort otherwise needed to adapt to different back-end systems. For this reason, composite applications should be loosely coupled to the components on which they are based, and act only as clients of the enterprise SOA services.

Consuming Enterprise Services Using Services Registry

The Services Registry (SR) is an open-standards-based registry for Web services. Located centrally within an enterprise SOA landscape, it contains entries for all services and service definitions in it, with references to the services’ relevant WSDL metadata and to the locations of the callable service endpoints. The registered services are classified using semantic-rich SAP classification systems to enable browsing of services by classification.

The SR provides visibility in an enterprise SOA landscape by answering questions such as where are services located, which services are modeled but not implemented yet, which services are already configured and can be called. The SR provides a simple but powerful, user-friendly means of discovering services in a standards-based way, which leads to the effective reuse of business services.
