Have a schema derived from object model, but only traditional DB tools?

Question

Have a customer name, need to find the orders he placed, and the line items of the orders? You need to enter 3 queries:
select * from customer where customer_name = ...
select * from order where customer_id = ...
select * from line_items where order_id = ...
Need to know more information about order related objects, have to enter more queries...
With SQL Edge, you only need to enter one query, and leave the rest to the tool.
