BlackBerry MDS Studio application and functional architecture components
Item Description
BlackBerry
MDS Studio
The BlackBerry MDS Studio is a graphical development tool in which application developers
design screen layouts, data elements, and application messages using a visual drag-and-drop
approach. Application developers can connect graphical components using wizards and
editors. Application developers can also connect to enterprise web service applications,
visualize supported operations, and generate a set of messages that they can use to interact
with enterprise data sources. The BlackBerry MDS Studio generates the required code to
transmit messages between BlackBerry MDS Studio applications and web services
applications.
Application developers can also use BlackBerry MDS Studio to customize application workflow
logic using JavaScript. When they complete an application’s design, the BlackBerry MDS
Studio automatically generates an Extensible Markup Language (XML) metadata
representation of the application.
Application
registry and
repository
Application developers publish completed applications from the BlackBerry MDS Studio to an
application repository, and system administrators register the applications with the
BlackBerry MDS Services on the BlackBerry Enterprise Server. After the applications are
published and registered, System administrators can make them available to BlackBerry
device users. Organizations can distribute the applications using one of the following
methods:
pushing BlackBerry MDS Studio applications to devices from a central console
enabling BlackBerry device users to search the registry through a device-side console
and download applications
BlackBerry
MDS Services
The BlackBerry MDS Services manage interactions between corporate applications and
BlackBerry MDS Studio applications on BlackBerry devices:
The connection service provides connectivity between the BlackBerry device application
and the application server.
The application integration service supports web services.
The provisioning service controls which applications users can download to their
BlackBerry devices and manages the installation of BlackBerry MDS Studio applications
on BlackBerry devices.
The administration and management service manages the policies that are associated
with the BlackBerry MDS Studio applications, and it centralizes application lifecycle
management.
BlackBerry
device
runtime
The BlackBerry MDS Runtime must be installed on the BlackBerry device before BlackBerry
device users can use BlackBerry MDS Studio applications. The BlackBerry MDS Runtime
provides the set of services necessary to interpret the XML that is produced by BlackBerry
MDS Studio and translate it into screen, data, and message components.
BlackBerry MDS Studio application features
Feature Description
Distributed
processing
resources
BlackBerry MDS Studio applications do not perform operations themselves; they define what
to do. The programmatic behavior is distributed among multiple external components.
On the application server, one or more web services contain the code to complete the
user tasks that the BlackBerry MDS Studio application provides and to support
operations such as binding, discovery, provisioning, and notification.
On the BlackBerry device, the BlackBerry MDS Runtime provides a generic set of
services such as screen handling, persistent data storage, and messaging for all of the
BlackBerry MDS Studio applications that run on a BlackBerry device.
This distributed processing model has several advantages.
