Thanks for viewing my post.
I have got a project about developing a website for different user and I am required to draw architecture diagram.
Can anyone tell me or show me example of architecture diagram? I need to diagram my 3 tier architecture diagram (Data Layer, Business Logic Layer and Presentation Layer)

Please help! Thanks.

There's no specified way to do that (as far as I know). Any diagram that indicates the various components and where they sit in relation to each other should be fine.
Just google 'n tier diagram' and you'll find plenty of examples.
