Abstract
A database processing device executes concurrent processing in accessing a database through a plurality of independent terminal units. The database processing device, upon updating data stored in a record after reading out the data stored in the record in the database and correcting or altering the data through a specific terminal, confirms whether or not the data stored in the record has been updated by terminals, and executes updating only when the data has not been updated. The data stored in the record includes update control information for confirming whether or not the data has been updated by other terminals.
