A data processing method and system for a database management system are provided. The database management system can reduce the number of log records to be processed and increase database processing speed by selectively assigning a “no log” attribute to a data table at the time of database creation and skipping log recording for data items having the “no log” attribute at the time of database processing. The data processing method includes identifying one or more attributes assigned to a column of a data table associated with a data item changed during processing of a transaction, writing, when the one or more attributes of the column include a “log” attribute, log records for the transaction to a disk, and skipping, when the one or more attributes of the column include a “no log” attribute, log recording for the transaction.
