Abstract
The present invention comprises a method of data synchronization between multiple devices by, in one embodiment, classifying one device to be a primary device and other devices to be subsidiary devices. Synchronization is performed, in one embodiment, by updating the primary device with data from the subsidiary devices, and then updating each subsidiary device using data from the updated primary device. The exemplary data synchronization according to the present invention can accommodate for absent devices, avoid redundant synchronization operations, accommodate for data truncation or translation and preserve synchronization of relationships. The devices may be any one of computers, handheld devices (e.g. a Palm device), personal digital assistants, music devices, and mobile telephones. The data to be synchronized may include any data, and even applications can be synchronized.
