The application, like a web site or a Windows Forms application is usually called the Presentation layer.
How do these business objects interact with other parts of the system?
- I have written a new series on N-Layer design targeting ASP. What's important to realize is that this is *my* take at layered design for web applications.
It builds on the foundation created in this first series, but digs much deeper into concepts like Validation, Sorting, Paging, Concurrency and Security. It doesn't feature all the necessary functionality your application needs, but instead focuses on the underlying concepts.
To get a general understanding of what a multi layered application looks like, consider the following diagram that shows a number of possible layers in a system.
This diagram describes a general process of an application that presents data that comes from a database.
So, you could for example drop the web site as the presentation layer and replace it with a Windows Forms application.
This change wouldn't require a change in any of the other layers. - I have written a new series on N-Layer design as a major follow up to this one. The design I am going to show you in these articles is a simplified version of a design you would use in a real world application. The target audience for this series are developers that are ready to make the switch from using controls with custom business objects. NET 2 and C# is necessary while some knowledge about object oriented design certainly helps.In this article series I'll show you how to design, build and implement reusable object oriented classes that are easy to use and maintain.The objects created from these classes are often referred to as business objects so that's the term I'll use in these articles.You know, the kind of sites many of you (including myself) are building right now.
