Hello all,

I'm developing a program but still having some issues to write a good
layered program wich includes presentation, business, and data layers. Can
some one suggest any good book, white paper, or article about it with case
study and clear examples writen in c#.

TIA

Is this a winforms or asp.net or something else?

I am in the process of writing such a book, but can't help now. Perhaps
I will blog something so you have an idea.

IMO, you need to think of UI as a faceplate, database as a storage
mechanism and app as the business logic that uses the data and has a UI
on top of it.

This is different from what you are asking, but it then leads you to
easy solutions (when you make the paradigm change). By focusing on the
business problem, you end up only building logic that solves the
problem.

I don't personally think you can get there without testing early (either
Test Driven Development (TDD) or Test Early Development (I will dub this
TED)), as you are a bit blind without the other "layers". But focusing
on logic also forces you to think about the communication between the UI
and the app and the data store and the app.

I will see if I have time at lunch to blog it.

Peace and Grace,

I take it a step farther and state the app is the business logic, the data
is a persitant mechanism and the UI is a faceplate for interaction. :-)

I have one sitting right here on my desk with the catchy title of

"Building Client/Server Applications with VB.NET: An example-driven
approach" by Jeff Levinson.

It's absolutely great. It explains everything you'd ever need to write every
single layer of an n-tier application and although it is writen with VB.NET,
it still explains how to make your app easily accessable by other languages
like java.

Thoroughly recommend it.

John.

It looks that OP is looking for advice on all layers, not just DAL. That was
my impression...

Thanks. I am working on a book idea that shows how to develop in this
paradigm. Do you think it might sell?

Actually you are right Miha. I read some articles about them and theory is
pretty clear, however implementation isn't that clear, for instance when I
use controls like textbox to bind to fields there is no problem, but if I
use a grid which can be editable the conection with the busines and data
layers are kind of confusing. I'm sure that everyone deals with it in their
own way, as I do myself, that is why I want to read other approaches to
find better ways.

So, what kind of application we are talking about?
