Embodiments of the present disclosure disclose a data synchronization method, system and apparatuses thereof. The data synchronization method includes the following processes: sending, by a client, a data characteristic verification message carrying one or multiple data characteristics for data in a client database, to a server; comparing, by the server, the one or multiple data characteristics carried in the data characteristic verification message with the data characteristics for the data in a server database; determining, by the server, the data to be synchronized based on a result of the comparing and sending the client a data characteristic verification response carrying information indicating the determined data to be synchronized. The method, system and apparatus thereof provided by the embodiments of the present disclosure can reduce the amount of data to be transmitted in data synchronization, and improve the efficiency of data synchronization.

Method and system for data synchronization, and apparatus thereof

Embodiments of the present disclosure disclose a data synchronization method, system and apparatuses thereof. The data synchronization method includes the following processes: sending, by a client, a data characteristic verification message carrying one or multiple data characteristics for data in a client database, to a server; comparing, by the server, the one or multiple data characteristics carried in the data characteristic verification message with the data characteristics for the data in a server database; determining, by the server, the data to be synchronized based on a result of the comparing and sending the client a data characteristic verification response carrying information indicating the determined data to be synchronized; and determining, by the client, the data to be synchronized according to the information in the data characteristic verification response, and synchronizing the determined data to be synchronized with the server. The method, system and apparatus thereof provided by the embodiments of the present disclosure can reduce the amount of data to be transmitted in data synchronization, and improve the efficiency of data synchronization.

Method for device capability negotiation, and method, system and device for synchronization. The synchronization system includes a synchronization server and a synchronization client. The synchronization server or the synchronization client is adapted to skip the device capability negotiation and directly perform a synchronization with the synchronization server and the synchronization client when the negotiated device capability or status ID, or the status ID indicating that the device capability has not been changed and has been stored. The method for device capability negotiation includes receiving an operation request carrying a parameter requesting a device capability negotiation; determining that the session is a device capability negotiation session according to the parameter requesting the device capability negotiation, carried by the request; returning a response and performing the device capability negotiation; storing results of the device capability negotiation. Embodiments of the present invention can improve the synchronization efficiency.
