Terms used in DOE-based application development.

You should be familiar with these software components and concepts before beginning DOE-based application development.

• BAPI – business application program interface; generally referring to a BAPI "wrapper." Contains the parameters required to synchronize the device data and the SAP back-end data.
• CDS – the consolidated data store. The SAP DOE middleware component where data is consolidated by the DOE.
• CUD requests – create, update, delete requests. All transactions from the application to DOE are called CUD requests.
• Data synchronization – the process by which the DOE reconciles changes in data on the device and data on the SAP back end.
• DOE – Data Orchestration Engine. The SAP component that supports data exchange between SAP back-end systems and mobile devices.
• DOE-C – the Sybase SAP DOE Connector. The Sybase component that connects applications running on Sybase Unwired Platform with the DOE.
• ESDMA – entity set definition for mobile applications. Contains the external metadata definition of a SWCV that you can use to construct a client that can interact with the DOE.
• ESDMA converter – the Sybase Unwired Platform utility that converts an ESDMA bundle into an Unwired Platform package that can be deployed to Unwired Servers.
• Gateway for Netweaver Mobile – Add-on that is installed on top of DOE to provide integration with Sybase Unwired Platform.
• Messaging framework – the messaging functionality provided by the Sybase SAP DOE Connector to connect the SAP DOE with devices.
• Mobile data model – relates the SAP back-end data and the data that ends up on the device.
• Persistence layer – the collection of database files, containing tables, that is available on the device through the Sybase Client Object API.
• Request/response requests – search queries sent to the DOE by the client application to retrieve data that is not delivered as part of the subscription data set.
• Subscription – defines how data is transferred between a user's mobile device and Unwired Server. Subscriptions notify a device user of data changes, then the updates are pushed to the user's mobile device.
• SWCV – software component version. A shipment unit for design-time objects in the DOE repository.
• Sybase Unwired Platform package – converted from an ESDMA by a Sybase Unwired Platform utility for deployment to Unwired Server, which makes the data available to client devices.
