Need help for doing a sample web based project and N Tier architecture

[silpa]

Hi,

I am new(or a learner) to web based projects and N Tier architecture.
I want to do a sample project on asp.net 2.0 with c#.net and SQL Server 2005
using N-Tier architecture for gaining knowledge.

The project I want to do is regarding Address Book.

I request you to kindly send me code for this if possible
containing data layer, business layer and UI layers.
Please help me in this regard.

Thanks,
Silpa

Presentation Layer
In the Presentation Layer, the code responsible for displaying user interface of the entire application is located. The common code placed in this layer are web forms. Web Forms consists of a .aspx file and .aspx.cs file.

In the Business Layer, the code that implements the business functionality of the Web ERP application is located. The business logic of an ERP application is implemented by using components.

The Business Layer also includes code responsible for accessing the Data Access Layer to retrieve, modify and delete data to and from the data layer and move the results to the presentation layer.

Data Access Layer
The code in this Data Access Layer exposes the data stored in the database to the Business Layer.

Data Layer
Data Layer is the database or source of the data. The popular databases are SQL Server, Access database and Oracle or can be XML.
