I'm developing 3-layerd web application. I have a Data
Access Layer with several Data Access Classes. Each class
is responsible for one kind (or several in some cases) of
business entity. I've implemented my business entity as a
custom class. In some Microsoft's articles is suggested to
use DataSet or typed DataSet or just Table for passion
data from Data Layer. I'm not asking what the best way is.
I'm just asking how people here implement this king of
architecture.
