Vb6 datagrid row cannot be located for updating - asynchronous updating cellular automata
This brings many advantages, including cleaner code, increased maintainability and the ability to spread your application's load over multiple servers.
The objects created from these classes are often referred to as business objects so that's the term I'll use in these articles. This is part 1 of the article series "Building Layered Web Applications" that shows you how to build N-Layer applications with Microsoft ASP. These articles teach you how to design, build and use custom business objects in your web application. For more information about the translation, check out this blog post. - 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.You know, the kind of sites many of you (including myself) are building right now.
Part one deals with the design of the application: what business objects do you need to fulfill the requirements of the application? - 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.What should these objects be capable of and how do they look?
