Building a 3-Tier Application Using ohwander.tk


By Nannette Thacker In web application development, three-tier architecture refers to separating the application process into three specific layers. What the user sees via a web browser is called the presentation tier and is content served from a web server. The middle tier performs the business logic processing that occurs, for 3-tier web application in asp.net, when a user submits a form.

The back end consists of the data tier which handles the database processing and access to the data. We'll take a simplistic look at each of these. Presentation Tier The Presentation Tier or User Interface is the 3-tier web application in asp.net the 3-tier web application in asp.net sees when they open a web page in the browser.

It is as simple as you reading this article all the way to searching a catalog and purchasing a product using a shopping cart. It is what is presented to the user on the client side within their web browser.

On some sites, you may see Java Applets and Flash. Viewing source code on a web page, you would NOT see database queries or loops or calls to classes or any behind-the-scenes processing. In ASP. As well, when creating a WebForm which 3-tier web application in asp.net the MasterPage, 3-tier web application in asp.net, you may create it and allow the code to be placed in a separate file, known as codebehind, thus keeping your business logic in a separate layer from the look and feel, 3-tier web application in asp.net.

Web languages typically used in ASP. In this layer you typically define your classes, functions, sub procedures, 3-tier web application in asp.net, properties, etc.

It is where you define your queries or stored procedures. The business tier may then make use of this functionality. In your classes, rather than defining ad hoc queries, you may use a TableAdapter to access the Data Access Layer. An Example As an example of how this works, let's assume you are creating a web page that allows the user to enter information which you wish to then enter into a database.

You first create a dataset and tableadapter that allows insert into the table, either by a query or stored procedure, 3-tier web application in asp.net. This is your data access layer. You then create a class, which retrieves the information from the form, checks for field validations and then uses the tableadapter to send the data to the database. You create a web form, 3-tier web application in asp.net, which can use a GridView control or other controls to allow the user to input the data into the web form.

In the codebehind of the web form, you handle the submit button click event, and send the data from the form to your class, which sends the information to the database using the tableadapter. Benefits When utilized properly, using a multi-tier architecture improves performance and scalability. If a web page needs an update or redesign, all of this may be handled by altering the CSS and HTML, without affecting the business or data logic. Any of the three tiers may be replaced or upgraded individually without affecting the other tiers.

For instance, if you change the database on the back end, it wouldn't affect the presentation or business logic tiers, other than changing the database connection. This is a simple introduction to the three-tier web architecture, but I hope it has helped you understand the layers of a multi-tier architecture.
