Developing Mobile Applications for Handhelds
Mobile Applications for Handhelds allow customers to mobilize their business processes for handheld devices, such as Personal Digital Assistants (PDAs). Handheld Applications target users, who need to access information while they are away from the office. Users can include sales executives, field service engineers, or delivery personnel, for example. These users occasionally connect to the Data Orchestration Engine (DOE) to synchronize applications and to exchange data. The DOE supports the data exchange between the Handheld and the back-end system.
Handheld Applications are based on dedicated Mobile Components, in which the data access, the business logic, and the UI are in separate layers. The Handheld Application itself is composed from these components, which serve as reusable entities across different scenarios. For small applications or test applications, explicit separation of layers is not mandatory and single-component applications can also be created. In either case, the user interface of Handheld Applications is built using Web Dynpro for Java, SAP's UI programming model for building professional business applications.
The Mobile Applications for Handhelds perspective is installed as part of the SAP NetWeaver Developer Studio on a development workstation.
