Handheld Applications Glossary

Term

Definition

Application Explorer

A view in the Mobile Applications for Handhelds perspective of SAP NetWeaver Developer Studio for modeling Mobile Applications

Data Object

Allows you to stage data relevant for mobile applications in SAP NetWeaver AS.

Data objects are imported from the Data Orchestration Engine (DOE) by deselecting nodes and attributes that are not required by the Mobile Service Component.

Compact Development Scenario

A development scenario in which business logic, represented by the Web Dynpro (WD) model, and UI, represented by the WD application and its components, are contained within the same development component

This scenario is typically used for sample or test applications. In this scenario, the WD model is generated by importing data objects from the Data Orchestration Engine (DOE) and adding queries and data structures as dedicated WD model classes.

Composite Development Scenario

A development scenario based on clear separation of business logic, UI, and composition

This is achieved through distinct, dedicated, and reusable mobile components reflecting these layers. It is typically used for productive Mobile Applications. In this scenario, the Web Dynpro (WD) model within the Mobile UI Component is generated from the structure of selected Mobile Service Components, which themselves represent the business logic of the mobile application.

Custom Operation

A Service Operation of which only the signature is modeled, but for which the implementation is programmed manually

Data Object Model

A Web Dynpro (WD) model type where the model classes are generated by importing data objects from the Data Orchestration Engine (DOE) and enhancing the model by adding data structures and queries

The Data Object Model is used in the Compact Development Scenario.

Handheld

A pocket-sized mobile computing and data-service device

Handhelds typically have a small display screen for user output and a miniaturized keyboard or touch-screen interface for user input. They include personal digital assistants (PDAs), BlackBerry devices, and smartphones, for example.

Handhelds UI Explorer

A view in the Mobile Applications for Handhelds perspective of SAP NetWeaver Developer Studio, in which the user interface (UI) is modeled for Mobile Applications

The Handhelds UI Explorer leverages standard Web Dynpro tools, while hiding all Web Dynpro (WD) entities and functionalities that are not supported by the Mobile Client for Handhelds.

Mobile Application

A SAP NetWeaver Mobile application developed in the SAP NetWeaver Developer Studio that offers business functionality for Handhelds

Such an application is composed from Mobile UI and Service Components to form a complete mobile application that is ready to use by end users. It holds references to the required mobile components and defines the links that appear on the application launcher of the Mobile Client for Handhelds.

Mobile Applications for Handhelds perspective

A dedicated perspective of the SAP NetWeaver Development Studio for developing mobile applications that run on Handhelds

It contains all required development tools.

Mobile Client for Handhelds

The front-end software for Handhelds, on which it is installed to run Mobile Applications for Handhelds

Mobile Component

An NWDI development component of type Mobile Applications for Handhelds

It is developed using the mobile tools provided in SAP NetWeaver Developer Studio and can be either a Mobile Service Component or a Mobile UI Component.

Mobile Service Component

A Mobile Component containing the business logic of a mobile application

It is modeled using the Service Explorer of the Mobile Applications for Handhelds perspective in the SAP NetWeaver Developer Studio and internally holds services, data objects, and data structures.

Mobile Service Component Model

A Web Dynpro (WD) model type in which the WD model classes are generated from the structure of the Mobile Service Components

The Mobile Service Components Model is used in the Composite Development Scenario.

Mobile UI Component

A Mobile Component containing the user interface (UI) of a mobile application

It is modeled using the Handhelds UI Explorer in the Mobile Applications for Handhelds perspective in the SAP NetWeaver Developer Studio. It internally holds normal Web Dynpro (WD) model entities.

Query

A Service Operation used to retrieve data from Data Objects

Service

A service groups Service Operation, such as a Query or Custom Operation, within a Mobile Service Component

Service Explorer

A view in the Mobile Applications for Handhelds perspective of the SAP NetWeaver Developer Studio, in which Mobile Service Components are modeled

Service Operation

Business logic on top of Data Objects and data structures within a Mobile Service Component

Two types of Service Operations are provided: Queries and Custom Operations.
