1. A data synchronization method, comprising:
- acquiring first update data for an update process performed on a first database;
converting the first update data into second update data according to a format of a second database based on previously set conversion definition information;
deciding a lock range based on the first update data and pre-update data that has not been subjected to the update process;
locking the first and second databases based on the decided lock range; and
updating the first and second databases using the first and second update data, respectively.
