Abstract

An application persistence system for improving wireless application resource efficiency is provided. The application persistence system comprises a persistence-point definition module for defining conditions that trigger persisting application data, a persistence-point analysis module for identifying efficient and reliable persistence points and a persistence points enforcement module for enforcing persistence points at application runtime. A method of improving wireless application resource efficiency is also provided. The method comprises the steps of defining conditions that trigger persisting application data, identifying efficient and reliable persistence points, defining a persistence mode flag in an application'"'"'s profile, and enforcing persistence points at application runtime.

Claims

1. An application persistence system for improving wireless application resource efficiency, the application persistence system comprising:

a persistence-point definition module for defining conditions that trigger persisting application data;

a persistence-point analysis module for identifying efficient and reliable persistence points; and

a persistence-point enforcement module for enforcing persistence points at application runtime.

2. A method of improving wireless application resource efficiency, the method comprising the steps of:

defining conditions that trigger persisting application data;

identifying efficient and reliable persistence points;

defining a persistence-mode flag in an application'"'"'s profile; and

enforcing persistence points at application runtime.

3. The method as claimed in claim 2, wherein the step of enforcing includes the steps of:

executing the application;

receiving notification that data needs to be persisted; and

determining if a persistence point of the application has been reached.

4. The method as claimed in claim 3, wherein the step of enforcing further includes the steps of:

determining if the application is running in reliable mode; and

persisting the data.

5. The method as claimed in claim 3, wherein the step of enforcing further includes the steps of:

determining if the application is running in reliable mode; and

determining if the current persistence point is an efficient point.

6. A computer-readable medium storing instructions or statements for use in the execution in a computer of a method of improving wireless application resource efficiency, the method comprising the steps of:

defining conditions that trigger persisting application data;

identifying efficient and reliable persistence points;

defining a persistence-mode flag in an application'"'"'s profile; and

enforcing persistence points at application runtime.

7. A propagated signal carrier carrying signals containing computer-executable instructions that can be read and executed by a computer, the computer-executable instructions being used to execute a method of improving wireless application resource efficiency, the method comprising the steps of:

defining conditions that trigger persisting application data;

identifying efficient and reliable persistence points;

defining a persistence-mode flag in an application'"'"'s profile; and

enforcing persistence points at application runtime.
