Data synchronization method and device, computer equipment, storage medium and program product

The invention relates to a data synchronization method and device, computer equipment, a storage medium and a program product. The method comprises the following steps: acquiring target data and source data to be synchronized in the electrical joint system, and performing data verification processing on the target data and the source data to obtain a verification result; and comparing data in the source data with data in the target data under the condition that the verification result characterizes inconsistency to obtain difference data, and modifying the target data according to the difference data so as to synchronize the source data and the target data. By comparing the source data with the target data, the difference between the synchronized data and the source data can be obtained, and the target data is repaired according to the difference. Therefore, an accurate data synchronization result can be obtained. Furthermore, the check values of the target data and the source data are compared firstly, so th
