A method and system are provided for sharing data amongst a group of a plurality of mobile devices without requiring a database or server to centrally store the shared data. The shared data is instead stored by each group member individually while controlling the manner in which the shared data is updated. To manage such updates, the shared data is atomized such that individual databases in the shared data are separated or otherwise delineated into one or more records, each record having associated therewith, a value. To maintain a common copy of the shared data at each device, any update is sent to all group members using an intermediate message exchange service that is capable of transmitting a sent message to more than one recipient if necessary. In this way, the updates are multicast to the group. To manage the content of the shared data, each update comprises one or more changes to a current copy of a corresponding record.
