Create a statement trigger called "bt_maj_adv_trigger" that would be work with both advisor as well as major table. If a record is inserted, deleted or updated in either of the table, the system will insert the user name, table name, date, and the dml command executed on the table. To insert this information, create an appropriate "log_maj_adv" table first before you create the trigger
