Well, I made application using postgresql database.... there is a list
of employee.... if user want to delete the employee data, I have to
check whether this employee data has been referenced or not.... if no
body need this employee data ( has not been referenced ), my application
will delete it... but if somebody need this employee data ( has been
referenced / maybe transaction table need it ), I just move the employee
data to not-active list of employee.....
