Life-Cycle of a Disconnected Business Application
In order to be successful, a programming model for disconnected devices must be
compatible with the life-cycle of a disconnected application.
Deployment of a disconnectable business application requires that an administra-
tor perform a one-time setup (life-cycle stage
0
) of the mobile device's database(s).
The key challenge in stage
0
is to replicate sufficient data (from the server to the
device) such that the application can execute correctly. This can be a difficult task
when an application can potentially access a data set that is too large to fit on the
device. In such cases, application administrators must determine the subset of data
