A method of synchronizing a first database including first data records with a second database including second data records includes receiving information representative of the second data records and modifying the first data records of the first database in a unidirectional synchronization with the second data records of the second database including deleting ones of the first data records present in the first database for which there is no corresponding second data record present in the second database.
