Three Tier Architecture with ASP.NET

  
ASP.NET supports layered architecture, and this article will illustrate how it can work with the ASP.NET presentation controls. This article focuses mainly on the GridView control, mostly because it is prevalently used in .NET development. However, the concepts work for other controls as well.

3-tier architecture in C# sample

  
This article discusses and implements 3-tier architecture using C# and a dummy customer using MS Access database. In this article I am trying to implement a small reusable component that maintains customers in 3-tier architecture. It shows how to add, update and find customer details.

Three Tier Architecture with ASP.NET

  
In my previous two articles, we talked about the use of layers, and the many different options that can be used to develop layered architecture. Layered architectures are essentially objects and work in object-oriented environments, such as ASP.NET.

Logic behind N -Tier Application Development

  
In the arena of application development, developers all over the world use various programming languages, technical processes, and technical tools. While using number of technical & non technical elements the processes or methods become complex, for simplification of the application development process, developers use various techniques such as dividing the application architecture into layers or parts. In the professional & technical language this separation or division process is called N-Tier Application Development process, where "N" stands for number and "tire" stands for layers or parts.

Building a 3-Tier App with Silverlight 3, .NET RIA Services, and Azure Table Storage

  
Silverlight 3, .NET RIA Services, and Windows Azure Services Platform makes a 3-tier Cloud application easier to build: Silverlight 3 as presentation tier, .NET RIA services as the business logic and data access tier, and Windows Azure Table as the data storage tier. The sample application in this article demonstrates the architecture with a simple Survey application with all these technologies working together from Windows Azure.

Which tier do Linq queries belong?

  

Started in middle of a new project.  Our design architecture uses an n-tier (not MVC - no controllers) structure with Presentation, Data, Business and Service tiers.  However the lead analyst has the majoriety of code all in the Business tier claiming it all contains Business logic.  Our data tier is nothing more than a single .dbml model of the primary database to support all of the Linq queries in the Business tier.  To my mind Linq queries and classes they use are data access and belong in the data tier  but our lead analyst says they contain business logic therefore have to be in business layer.  


3 tier architecture in ASP.NET

  

Hi i want to develop an application in asp.net using 3 tier architecture . 

i know that there are three layers

  1. Data layer
  2. Business Layer
    1. Data Access Layer
    2. Business Logic Layer
  3. Presentation Layer

I am confused between Data Access Layer and Business Logic Layer.

In data access layer we develop the property classes and main class function which returns datasets, datatables and data reader to Presentation layer.

what is the use of Business Logic Layer ? what actually we do in Business logic Layer ?? we can pass data directly from data access layer to presentation layer ?? can anyone give any small example to understand ??

Authorize It: Use Role-Based Security in Your Middle Tier .NET Apps with Authorization Manager

  

Authorization Manager in Windows Server 2003 represents a significant improvement in the administration of role-based security, making it more scalable, flexible, and easier to implement. Using Authorization Manager, you can define roles and the tasks those roles can perform. You can nest roles to inherit characteristics from other roles, and you can define application groups. In addition, Authorization Manager lets you use scripts to modify permissions dynamically, and it allows you to wrap your security logic in a security policy that can be stored in Active Directory. Authorization Manager also includes an easy-to-use API for running access checks. The author discusses all of these topics and demonstrates them with a working sample.
