摘要
Disclosed is a method for transmitting data for data synchronization between a server and a client. If a data synchronization session in a network is abnormally terminated, the client stores state information of data to be transmitted, which indicates states of the data at the time of the abnormal termination. The state information of the data makes it possible to resume the data transmission beginning with data items that were being transmitted at the time of the abnormal termination. Since one of the server and the client transmits only data that has not been received by the other, it is possible to decrease the time necessary to complete the data synchronization and also to reduce a wasteful, unnecessary transaction when synchronization of a large amount of data is performed.
