Meaning we should be able to review and approve row changes and migrate to test and production. I know there are data replication tools such as Streams, Data Guard, SharePlex etc. but those tools replicate at redo log level or do not have review/approval logic. Any input in this regard is highly appreciated. Thanks, Muru -- //www.freelists.org/webpage/oracle-l
