N-Tier Applications and .NET: A Simple Example
Many days back I wrote an articled titled
Applications and .NET with an explanation of basic concepts involved in
developing N-Tier application. I received feedback from many many readers that
they liked the article and requested a sample application illustrating the
concepts discussed. Here is that sample!
The sample application consists of three projects
The first project represents a presentation layer, the second and third
layers represent business logic layer and data access layer respectively.
The sample consists of a simple web form that acts as a data entry screen for
Customers table of Northwind database. The form allows to Insert, Update and
Delete records to the Customers table.
Downloading and running the application
You can download the complete source code above (see top of this article).
Before you run the application at your end make sure that the web application
project is marked as IIS application. Also, ensure that the database connection
string is changed as per your requirements.
