1.SAP's commercial scheme is built on a modular multi-stage client framework that is highly transferable to the newer Service-Oriented Architecture (SOA) offered in the computer's most recent editions. It is a customer interaction at the initial layer, which is a browser-type graphical user interface (GUI) executing on a mobile device. This program sends a request from consumers to the database servers. This stage of SAP represents the presentational layer, where it consists of the client interface component; the component procures the user input to process it to the application, which plays the role of the middle stage of the system, which is responsible for acquiring and processing customer queries.
