OK so the way I look at this is as follows:<br />
<br />
Presentation layer - ASP.net &nbsp;(interface)<br />
Business layer - vb.net (code behind, logic)<br />
Data Layer &nbsp;- SQL server<br />
<br />
Am I thinking of this correctly? &nbsp;This is what I have always done for an intranet application I developed (developing).

I have a general question that I need cleared up. &nbsp;I have read several sources about web application design and the architecture used. &nbsp;3 layers of development are typically used - presentation layer, business (logic) layer and data layer. &nbsp;The only question I have is as follows: &nbsp;Up to this point I have only used SQL server (data layer) and asp.net with vb.net code behind - my question is with ASP.net is that not the presentation layer of the development environment I am working with?<br />

Could someone please make this clarification for me?<br />

Multilayer web application design

Microsoft SQL Server is a suite of relational database management system (RDBMS) products providing multi-user database access functionality.SQL Server is available in multiple versions, typically identified by release year, and versions are subdivided into editions to distinguish between product functionality. Component services include integration (SSIS), reporting (SSRS), analysis (SSAS), data quality, master data, T-SQL and performance tuning.

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications

SQL (Structured Query Language) is designed to be used in conjunction with relational database products as of a means of working with sets of data.
