3. Topics to address in the ‚Enterprise‘ space • Framework level related topics • Life Cycle ManagementThe control of the complete lifecycle of devices and their respective services is key • Device profiling • Service profiling • Business Process Modeling ‘Interpretation’Modeling new business processes needs to result in ‘deployable’ bundles • Programming model • Meta Language • Semantics

4. Topics to address in the ‚Enterprise‘ space • Framework level related topics • Supportability, Supportability, SupportabilityThe remote support of business applications at customer side is one of the key successors in the enterprise space. • Remote management, Remote debugging, Remote monitoring, etc. • ExtensibilitySAP applications are customized and extended in almost 100% of all cases • Patches, Extensions, Updates, Versioning • Network connection awareness (general topic)Many useful functions are only possible if you know more details about the current state of the connection to the network. • Network connection state awareness • Network connection bandwidth awareness • Connected and offline support

5. Topics to address in the ‚Enterprise‘ space • Application level related topics • Data synchronization & data persistenceEnterprise applications often require the availability of data even if the client is not connected to the network. Those data must retrieved, locally stored & changes must be synchronized with the backend later on. • InternationalizationThere is no application at SAP which is not available in many languages. • ConnectivityBeside remote connections to management systems there is a huge demand to access also remote functionality. • WebServices, XML-RPC, etc. • Security • Security • Certification of services

6.
