I have a small problem setting the permissions for my data. Actually my application allows specific users to manipulate selected tuples stored in the same tables. Therefore, I revoked all privileged on the tables and encapsulated them through views based on the user variable. This way specific users control specific data.
The problem arises when I try to lock my data once it was validated. Although I set the permissions on the views to select and revoked the insert, update and delete privileges; my users are capable of modifying the table through the views. I even tried to revoke the select permission but this does not solve the problem.
