Default using Custom Entities in 3 layer?

I building website as 3 layer
but I have a problem
Example: I have 3 table
1> Custommer: Id, Name,Telephone,Address
2> Product: Id, Name, Price, Status
3> Order: Id, IdProduct, IdCustommer

When I get Data from one table, such as Custommer, I use BLL
List<Custommer> lst = CustommerBLL.GetLists(); => that'ok

But when I want to get Data from 3 table (get OrderList include customer'Name and Product's Name), how can I use Custom Entities.
In this situation, I have to using Dataset to get all of Information from 3 table

I don't want to use Dataset
Do u have any way for this situation
Help me, thanks a lot
