Abstract
Disclosed is a data replication method in a Database Management System (DBMS). The data replication method includes generating a replication log through a transaction log of a master database to thereby transmit the generated replication log to a distributor, determining a slave host distributing the replication log to thereby distribute the replication log to the corresponding slave host, and reflecting the replication log in a slave database.
