A data synchronization method applied to data synchronization between heterogeneous databases includes a terminal device that records a primary key, attribute information, a version number, and a synchronization status of a data object using a first storage format, and a cloud device that records a primary key, attribute information, and a version number of a data object using a second storage format such that the terminal device and the cloud device implement data synchronization between the heterogeneous databases based on the storage formats and version numbers.

Data synchronization method and device

A device-cloud collaboration method, platform, and apparatus, where the device-cloud collaboration method includes: obtaining current spatial information of each target terminal; tracking a spatial information change of each target terminal, to obtain a spatial information change status of each target terminal; and determining, based on spatial information-based arbitration conditions preset for different target mobile applications and the spatial information change status of the target terminal corresponding to the different target mobile applications, whether to trigger subsequent operations related to the different target mobile applications. The device-cloud platform blocks a change in which the user is not interested through arbitration of a spatial information change of the user, and provides an appropriate spatial information change to a mobile application, or triggers a subsequent operation of the mobile application.
