The delta detection routines are the triggers within the enhancement framework that detect modifications to data of concern to the mobile application. When changes are made to production data in the back end system, the delta detection routines will capture the change event. If a given change is one that will affect the data in the mobile application, then the routine will update the appropriate exchange table in the mobile exchange persistent layer. Intelligence is incorporated in the delta detection routines to determine if a change is one of concern to the mobile application. If it is not, then the change is ignored by the routine.
