Abstract: The battery powered mobile computing device has a local database which eliminates the need for an application or user interface program on the device to poll the database for changed data by instead continuously pushing data that has changed in the database to that application or user interface program for that application or user interface program to display. The data that is continuously pushed is preferably only that data which the application (or UI program/component) defines as being needed-for example, needed for display. This approach is better than conventional approaches that use intrusive prompt screens since it is an automatic background process; it is better than automatic background approaches which require the application to regularly poll the database even when no data has changed since it uses power and processing cycles only when there has been a data change that in fact needs to be displayed.
