@padas, &nbsp;Ok, NP.<br />
I was intended to help the asker to go with 3-tier architecture way to build the apps. &nbsp; I was involved 3 months C# project with 3 tier architecture. So I just posted information about the idea. &nbsp;Anyway, let me provide more details later when I start post an answer.

Back in 2003 I used to separate code into a BL logic on a namespace like<br />
<br />
CompanyName.BuisnessLogic<br />
<br />
This code was mostly database calls<br />
<br />
I have been out of the software industry for some time and wanted to know if this is still best practice<br />
I read a lot about loosely coupled architecture, and was wondering what other ways there are and what I should be following<br />
Using .net 4.5

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

ASP.NET

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
