Abstract
Methods, systems, and apparatus, including computer program products, for synchronizing database changes among multiple devices. In one aspect, a method includes determining one or more primary differences between a primary database and a local synchronization database; receiving, from a secondary device, one or more secondary differences associated with a secondary database; merging the primary differences and the secondary differences to generate a set of merged differences; providing the set of merged differences to the secondary device; receiving, from the secondary device, an acknowledgment indicating receipt of the set of merged differences; and updating the primary database in accordance with the set of merged differences after receipt of the acknowledgment. Further, at least one conflict can be detected between the primary differences and the secondary differences, and can be resolved prior to generating the set of merged differences.
