business logic - best practices for web app

Back in 2003 I used to separate code into a BL logic on a namespace like

CompanyName.BuisnessLogic

This code was mostly database calls

I have been out of the software industry for some time and wanted to know if this is still best practice
I read a lot about loosely coupled architecture, and was wondering what other ways there are and what I should be following
Using .net 4.5

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

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

Yes it is still in use today. In fact if you are building a new web application you are better off using ASP.NET MVC as it encourages proper separation of UI, business logic and storage (e.g. SQL database)
