Answer 1

create or replace view
vns as
select e.department_id,e.last_name,d.department_name
from employees e,departments d
where e.department_id=d.department_id;
create or replace trigger trgg
instead of insert on vns
for each row
declare
cnt number;
begin
select count(*) into cnt from employees where department_id=:new.department_id;
if cnt=0 then
--insert into employees(department_id,last_name) values(11,'nandu');
insert into employees(employee_id,email,hire_date,job_id,department_id,last_name)
               values(207,'[email protected]',sysdate,'AC_MGR',11,'nandu');   --- Values you have to choose!!
end if;
select count(*) into cnt from departments where department_id=:new.department_id;
if cnt>0 then
insert into departments(department_id, department_name) values(11, 'wrestling');  -- department_id is needed
end if;
end;
-- testing with existing dept id = 10
insert into vns(department_id) values(10);
SQL> select * from departments where department_id = 11;
DEPARTMENT_ID DEPARTMENT_NAME                MANAGER_ID LOCATION_ID
           11 wrestlingRequirement you must be knowing well
Just showing you, how the trigger should be as per your view and logic inside trigger or you re-create view to avoid required values in trigger body.
thanks!
