yes I know the method for implement, but I do=   not know where I should implement necessary changes ....
I know t= hat I should add a additional column in my data base tables that show the l= evel of access of each row.
these level types is finite.
and by the= way I should add to a sql command which user issues, the condition that it= checks whether he / she can access / gain the row he/ she want or not. But I don't know these two steps how and where I should implement.

Have you research the BLP mo= del? That's what I would do first. Google it.

However even before th= at you should discuss this with your supervisor,
who no doubt has someth= ing in mind and can and should give you
references to follow.
