Abstract: A terminal, a storage medium, and a database synchronization method thereof are disclosed. The database synchronization method includes reading data from a first database and capturing a dynamic data log in the first database; joining data to a waiting queue read from the first database; determining a dislocation category of the data in the waiting queue, and rearranging the dislocation data in the waiting queue into a first category according to the dynamic data log; and synchronizing the rearranged data to a second database. According to the database synchronization method provided by the present invention caches the data read from the first database to the waiting queue, and dislocation data in the waiting queue is rearranged and then synchronized to the second database, so that a problem of poor data identity after database synchronization is avoided.
