When the back-end enterprise system includes the Data Orchestration Engine (DOE) component of SAP NetWeaver Mobile, DOE data objects define the mobile data model for Object API Applications. DOE consolidates data from diverse SAP back-end sources and distributes it to applications via Sybase Unwired Platform messaging.
DOE-based applications, working in conjunction with Sybase Unwired Platform, allow system designers to model and consolidate SAP mobile content in the middle tier, while separately layering distribution rules over this content. This approach is especially useful when back ends cannot provide a mobile interface that serves up mobile data, or if additional flexibility is required. Distribution rules can evolve separately from the content model, and different distribution rule sets can be used with the same content model.
