Abstract
A data management system and a method for managing copies of a shared data file maintained on a plurality of computer systems that are connectable via a mobile communications network. The method comprises: for each copy of the shared data file, maintaining a record of modifications made to that copy; retrieving, via connection to the mobile communications network, the records maintained for other copies of the shared data file; merging the retrieved records to generate a sequence of modification; applying predefined rules to the sequence of modifications to resolve conflicts within the sequence of modifications; and modifying the copies of the shared file based on the conflict-resolved sequence of modifications. The solution is not restricted to a particular set of applications. It improves efficiency since it retains communication autonomy from the applications. Applications need not be modified to make use of the facilities provided.
