Abstract
A system in a processing device having at least one application including application data in a format in an application data store. The system includes: a system data store associated with the processing device including a representation of a previous state of application data in the application data store; a difference engine generating difference information associated with a change to said application data store; and an application interface, interpreting application data for the difference engine. The difference engine may further comprise a delta engine comparing the change to said application data store to said system data store to construct difference information. In a further aspect, a method for updating data files in a first system is provided. The method includes the steps of providing a data store associated with the first system and including information representing data in the data files at a previous time state; generating first difference information upon a change to the data files by comparing the change to the data store; receiving second difference information for a subset of said data files from a second system; and applying said difference information to said subset of said data files.
