What is a Online Mobile Application?

Works directly with backend - Provides information needed to the end-user on a request–response paradigm, Its user driven on demand information access

Updates work without delay and possible synchronization issues

No business data on the mobile device

Typical examples include approvals of business requests, inspection of real-time data of backend systems, incident reporting such as quality issues


Characteristics of Online Apps Architecture Fundamentals and Components

Architecture for online apps follows REST

(Representational state transfer, architecture style of

the internet)

Business data is transferred by request of the client,

no push of business data, but push notifications using

minimal payload

OData is an open standard that is defined by

Microsoft in collaboration with SAP

OData defines how meta-data and data is exchanged

between client and back-end

OData is based on HTTP and Atom

Back-End

Middleware

Mobile App

Mobile app renders data

and controls interaction

with the user

Middleware is for

infrastructure tasks but

not used as run-

time/design-time

environment for

application code

Back-end stores data,

executes business logic

and exposes data in the

structured in a way that

suited the client

Key benefits of SUP for online applications

Reliable messaging & Push Notifications

Comprehensive client SDK

Extensive supportability toolset

Registered endpoint management

Device Agnostic from application stand point

Integration with Afaria

– Automatic settings provisioning

– X.509 certificate provisioning

Security

– Prevents DOS attacks

– Payload encryption

– Secured data on device with data vault

New in SUP 2.2


Mobile Service REST API

REST API exposes the Mobile Platform features as

services which can be consumed from any HTTP-enabled

SDK

Onboarding

Authentication & SSO

Push

Configuration

Reporting

The REST API support the ‘online’ use cases:

NW Gateway

HANA and other ‘Concept Gateway’ sources

Other Web Service backends

Applications can connect to these

services regardless of whether SAP has

shipped libraries for that SDK.

For example, using the REST API and

the Windows 8 SDK and Visual Studio,

with no SAP client-side libraries, the

developer can build a fully integrated

enterprise-grade application on the

platform.

The developer may also use the

services with client libraries provided on

supported OS’s.
