SAP NetWeaver: the architectural solution for integration

The management of complex and multitier enterprise informative systems obviously affects costs and often limits evolution of applications.

The most proper solution in response to the rationalization problems is represented by the SOA model.

In a services and integration oriented architecture the business functions are provided by specialized systems and exposed by means of a standard public interface.

The central elaboration unit becomes the "service" seen as the reusable software module, used through an interaction of request/reply type, that executes a business function in an atomic way. Therefore, the services are modular elements – to be composed as needed – and the architecture guarantees interoperability independent from the peculiar technology the services themselves are realized with, or “natively” exposed to users.

Thanks to the Web Services introduction, that are today a standard de-facto for the platforms interoperability, the Internet capillarity is exploited to provide access to the applicative services.

The outstanding benefit deriving from the SOA model relies on the drastic decrease of the infrastructure complexity in general. Another fundamental advantage is that it gets simpler for informative systems belonging to external subjects, such as partners or suppliers, to be comprehended inside the structure, that is to be integrated in processes.
