Page and Record level Authentication / Access control.

Question

Hi,
I hope some of you might have come across this kind of issues. I am trying to setup page level authentication and record level access control. Please see below for the detailed description.
1. Does APEX have any functionality where I can implement my page level authentication schemes.
Say there are 5 pages/tabs and 10 users, and I want to restrict access as follows.
All users can read the data in all the pages.
User 1 thru 8 can read all the pages and edit page 1 and 2
User 9 and 10 can read and delete the records inside the page.
2. Is there any mechanism, that supports record level access control.
Example : There is a page, it shows a product information of all the products. Is there a mecanism inside APEX wherein this page shows only the products created by it's creater (any end user)
Is there a way in APEX, we can implement this functionality without having user information stored in the DB. ?
Thanx in advannce.
Vijay.

Vijay,
When a user creates the product why not store the user who created it in a column in the same table. That way you can write something like this:<BR>
CREATE TABLE products_tab
  productid NUMBER PRIMARY KEY,
  product_name VARCHAR2(200),
  user_created VARCHAR2(30)
);<br>
SELECT
  productid,
  product_name,
  ( CASE
      WHEN user_created = :F_USER THEN
        --link to edit page goes here
      ELSE '<nbsp>'
    END ) edit_link,
  ( CASE
     WHEN user_created = :F_USER THEN
       --link to delete page goes here
     ELSE '<nbsp>'
    END ) delete_link
FROM products_tab<br>
I don't believe you can use an authorization scheme on a button the way you desired. It either displays the column or it doesn't.<br><br>
Hope this helps.<br><br>
