OData SDK Applications are simple, mostly online mobile business applications that leverage standards-based approaches—OData protocol and RESTful Web Services. This approach provides instant quick value applications meant for end user productivity.
OData SDK applications are developed to leverage a proxy connection to SAP EIS systems, such as SAP Business Suite, and are deployed using the Online Data Proxy runtime option, essentially making realtime SAP data available to device users. The proxy connection uses the RESTful OData protocol to connect through Unwired Server and SAP Gateway to SAP enterprise information systems. Data is made available using a request-response pattern, without synchronization.
OData SDK applications running on mobile devices use semantic annotations to tell the client which of the OData properties contain specific data, such as a phone number, a part of a name or address, or something related to a calendar event. This allows seamless integration with contacts, calendar, and telephony on the mobile device. A metadata document defines whether an entity set is searchable, which properties may be used in filter expressions, and which properties of an entity will always be managed by the server.
