Still new to the MM framework and have I few questions:
Why was the sample application made to display the primary key of the products table instead of the product description in the datagrid?

What is the recommended way of line item data with its n:1 related items?
In the sample application, would the best choice be to add the products table to the SQL on the GetOrdersByCustomerID() to proivde the item description or should a separate business object be made for the products table that gets joined at the with the result of the order detail business object?

Thanks,
