| description | The present invention provides a method and a device for recovering a database when a conflict occurs in the database applying a journaling method using an original database and a replicated database replicating the original database. According to an embodiment of the present invention, the method for recovering a database comprises the following steps of: obtaining change information which indicates a change state of the database from each of the original database and the replicated database replicating the original database; obtaining transaction information including information on whether a transaction performs which reflects the change for the original database in the replicated database; and selectively recovering the original database based on at least one among the replicated database, the change information and the transaction information.
