Is this right pls?

And isd the diagram I am appending be okay since I have added a business log compartment?
Do you have a separate set of classes that contain methods which in turn perform database calls or do your forms perform the database calls? Because whether you are calling SPs or using inline SQL - if it's a call made from inside your form's code, then it's 2-tier. If you've got a separate class that contains methods, and your form uses this middle class, then it's 3-tier. In your case, I'm pretty convinced that it's 2-tier, so that diagram is wrong.
