The Integration Strategy of SAP 

Integration Between Different Systems

Business processes reach beyond system borders. This means that, as a developer of business programs, you often work with scenarios that cover several systems at one time. Therefore, it is necessary to be able to address functions – also called services – in another system or, viewed from another perspective, to be able to provide functions for other systems.  The strategy in this case is to provide the desired function as a Web service and to consume it on the client side as a Web service.

What Are Web Services?

A Web service is a modularized function that can be executed independently. You can call a Web service from any system using a standardized protocol. We distinguish between the Web service provider – a server that provides certain services – and the Web service consumer, who consumes certain services as a client. When you call a Web service, you pass on input parameters and the data is returned to you in output form.
