One thing you have to remember when looking into using
castor for db access is that there is almost no work

any but trivial schema.

Hi,

to arrange business logic, so it doesn't depend on
order or the order can be achiev

however LineItem class is abstract with 2 different
subclasses: ConcreteLineItem1, ConcreteLineItem2
I have tables for each: Order, LineItem,
