Hello Coder-X,
Following to the type of the question the general idea to excract common
entities to isolated business&data tier/layer that will have access to database
and give access of your application directly to this layer/tier, not the
database.

To get more comprehensive answer try to detalize your ambient: where is database
location,
who and where will work localy and remote, intranet only or not?

Hi,

the database will be located locally and should be accesible not only in the
Intranet but also in the Internet.
The Windows Forms UI will be located anhywhere in the Intranet .

Hello Coder-X,
I recomend you to try this: as I described in previous email to gather main
logic in business layer and move DB related code to the data access layer.
This gives u a lightweight client.

Local user will work with data layer directly.

For internet users u should create facade classes for your business layer
personified as WebServices. All internet users should work only with them.

Take into account that it's only a guide where u have to move.
There is a lot of thing to take into account: reliability, security, transactions.

Try to read Martin Fowler books, he is an expert in this.
