Hello Fawzia, What exacltly these "serious negative implications" are? Basically, any implementation of transparent cascade deleting can cause problems. Like unintentional data loss, locking problems, mutationg table problem. Another transparent procedure may be implemented using triggers. However, the same problems arise, but you will have more control. You can also write interface procedure to delete records instead of using directly DELETE statement.
