How to track column level value change in oracle using procedures

Question

I would need to write the below code using oracle stored procedures & packages.
DBA hates triggers so i cant enforce the same code.
Please help me out to achieve the same. thanks in advance.
if i do DML on master table (emp) , the audit should go to the emp_audit.i have used triggers but oracle DBA dont want to use triggers. Please guide me.
Master table : emp
column 1 : emp_id
column 2 : salary
create or replace TRIGGER test
AFTER INSERT OR UPDATE OR DELETE ON emp
FOR EACH ROW
BEGIN
IF INSERTING THEN
INSERT INTO emp_audit
(emp_id , salary,created_ts,CREATED_user,MODIFIED_TS,MODIFIED_usER, archived_ts, event_cd)
VALUES (
:NEW.emp_id,
:NEW.salary,
:NEW.CREATED_TS,
:NEW.CREATED_user,
:NEW.MODIFIED_TS,
:NEW.MODIFIED_usER,
systimestamp, 'C'); -- INSERT
ELSIF UPDATING THEN
INSERT INTO emp_audit
(emp_id , salary,created_ts,CREATED_user,MODIFIED_TS,MODIFIED_usER, archived_ts, event_cd)
VALUES (
:OLD.emp_id,
:OLD.salary,
:OLD.CREATED_TS,
:OLD.CREATED_user,
:OLD.MODIFIED_TS,
:OLD.MODIFIED_usER,
systimestamp, 'U'); -- UPDATE
ELSIF DELETING THEN

i am sorry.
we can't change master table emp structure.
Audit table would be emp_audit.
Please guide me to write some generic procedure to handle the audit , what ever insert/update/delete.
Please do the needful. thanks in advance.
Master table : emp
column 1 : emp_id
column 2 : salary
Audit Table : emp_audit
columns:
emp_id ,
salary,
created_ts,
CREATED_user,
MODIFIED_TS,
MODIFIED_usER,
archived_ts,
event_cd
create or replace TRIGGER test
AFTER INSERT OR UPDATE OR DELETE ON emp
FOR EACH ROW
BEGIN
IF INSERTING THEN
INSERT INTO emp_audit
(emp_id , salary,created_ts,CREATED_user,MODIFIED_TS,MODIFIED_usER, archived_ts, event_cd)
VALUES (
:NEW.emp_id,
:NEW.salary,
:NEW.CREATED_TS,
:NEW.CREATED_user,
:NEW.MODIFIED_TS,
:NEW.MODIFIED_usER,
systimestamp, 'C'); -- INSERT
ELSIF UPDATING THEN
INSERT INTO emp_audit
(emp_id , salary,created_ts,CREATED_user,MODIFIED_TS,MODIFIED_usER, archived_ts, event_cd)
VALUES (
:OLD.emp_id,
:OLD.salary,
:OLD.CREATED_TS,
:OLD.CREATED_user,
:OLD.MODIFIED_TS,
:OLD.MODIFIED_usER,
systimestamp, 'U'); -- UPDATE
ELSIF DELETING THEN
INSERT INTO emp_audit
(emp_id , salary,created_ts,CREATED_user,MODIFIED_TS,MODIFIED_usER, archived_ts, event_cd)
VALUES (
:OLD.emp_id,
:OLD.salary,
:OLD.CREATED_TS,
:OLD.CREATED_user,
:OLD.MODIFIED_TS,
:OLD.MODIFIED_usER,
systimestamp, 'D'); -- DELETE
END IF;
END;
