SAP NetWeaver Gateway

SAP NetWeaver Gateway is a technology that provides a simple way to connect devices, environments and platforms to SAP software based on market standards. Completely flexible, SAP NetWeaver Gateway offers connectivity to SAP applications using any programming language or model without much need for SAP knowledge by leveraging REST services and OData/ATOM protocols.

SAP NetWeaver Gateway liberates your SAP data to create engaging, custom solutions with “Anywhere World Class UX”. It lets you empower users with secure, personalized solutions that leverage and extend your existing SAP infrastructure. The easy-to-use framework helps you generate new opportunities and create richer connections with consumers, employees, and partners.

NetWeaver Gateway Architecture

NetWeaver Gateway sits above your existing SAP backend infrastructure, providing a wide variety of connectivity options to the SAP backend. The provided tools enable you to consume SAP data through a variety of user interfaces.

SAP Gateway utilizes your existing SAP infrastructure investment providing different deployment options. It offers strong, built-in security, automated governance, comprehensive monitoring and secured connectivity.

It provides easier, faster data consumption from SAP Business suite, SAP HANA and other SAP business applications on any device, anywhere, at any time.

SAP Gateway provides standard tools for service provisioning which allow generation of services which can be consumed easily on any device and on difference experience. Consumption of service from SAP Gateway need no or minimum SAP experience.

Generally Web Services are SOAP based, where SAP Gateway is REST-based.  SAP Gateway focuses on consumption scenarios and SOAP is more process-to-process, and machine to machine usage.

OData is a Web protocol for accessing structured data following the REST architecture principles. It builds on the AtomPub and JSON standards to allow easy consumption of data by a wide range of devices and client technologies. OData is called the “ODBC for Web” and provides Create, Retrieve, Update and Delete (CRUD) via HTTP protocol. SAP Gateway enables SAP functionality through OData protocol making it simple to access by developers without SAP development knowledge.

REST is an architectural framework and methodology which is based on addressability, statelessness, connectedness and uniform interface. OData is an implementation of REST.

SAP Gateway provides a way to translate existing SOAP service into OData for usage in user centric scenarios,
