3-tier architecture in an asp.net project

Question

I have an asp.net project, I created three folders under the root. The folder names are: "UI", "Logical" and "DataAccess". The correspond codes are seperated into different folders. For example, UI folder contains only presention, DataAccess contains how to retrieve dataset from database.

Can we say it is a three tie architecture?

The fact that you created some folders doesn't mean anything yet in terms of architectural pattern. You seem to have mentioned some, I quote, `corresponding codes` but without providing more information about this code your question hardly makes any sense. — Darin Dimitrov, Sep 26 '12 at 14:33

Title says ASP.NET, tags say ASP.NET MVC. Which one are you talking about, sir? They're a little bit different when layering them. — Display Name, Sep 26 '12 at 14:38

For me it is important to impose a physical separation to your layer.

So create library for Logical

So create library for DataAccess

And Presentation Project for UI.

Nota :

That permit to easy your layer, without use all yours composants.

If you want re use just your Logical , you can reference just your layer.

You create a low coupling, it can reduce the impact of a bug in an application

I found that this book helped me organise my layers correctly:
