The invention discloses a data processing method and an electronic device, and belongs to the field of computers.The data processing method includes the steps that mirror image data for describing goods is obtained; mapping relationship fields are read form the mirror image data, wherein the mapping relationship fields are used for describing the mapping relationships between the mirror image data and original data; according to the mapping relationship fields, whether the mirror image data is the same as mirror image data prestored by a system or not is judged; if the mirror image data is different from the mirror image data prestored by the system, the mirror image data prestored by the system is updated through the mirror image data, and the updated mirror image data is sent to devices related to the goods.According to the data processing method and the electronic device, whether the mirror image data is the same as the mirror image data prestored by the system or not is judged, the mirror image data prestored by the system is updated, the updated mirror image data is sent to the devices related to the goods, and the data processing efficiency of a database is improved.
