A data synchronization method and a data synchronization device

The invention relates to the technical field of database synchronization, and provides a data synchronization method and a data synchronization device. The data synchronization method comprises the following steps: obtaining a backup file generated by a source database by a source synchronization tool; Sending the backup file to the destination synchronization tool so that the destination synchronization tool can restore the reference database and the active transaction log according to the backup file; Obtaining the maximum log sequence number corresponding to the source database at the backup completion time; reading the operation log whose log sequence number is larger than the maximum log sequence number in the log file of the source database, and sending the operation log to the destination synchronization tool, so that the destination synchronization tool synchronizes data on the destination database according to the reference database, the active transaction log and the operation log. The data synchronization method of the invention does not need to perform a rollback operation on the active transaction, and the data processing amount is reduced. At the same time, there isno need to limit the transaction commit time and the backup start time, which can effectively improve the efficiency of synchronization.

The manual mode of prior art for identifying white spirit has problems of low efficiency, higher identification cost, accuracy affected by the subjective element of the identifier and the like. According to the invention, the name, odor type, manufacturing year, degree number and reference characteristic parameter of each reference white spirit are stored in the reference data base. Subsequently the fluorescence spectrum of the white spirit to be identified is measured and is prepared to a three-dimensional fluorescence spectrum. The comparison characteristic parameter is extracted. The reference characteristic parameter which is same or most approximate extracted comparison characteristic parameter is inquired in the reference data base, and then the name, odor type, manufacturing year, degree number and reference characteristic parameter are acquired. Then the similarity between the white spirit to be identified and the reference white spirit is calculated out according to the extracted comparison characteristic parameter and the acquired reference characteristic parameter.
