Hello,
I'm trying to create a simple warehouse app on GAE, but I'm stuck with
the design of my models.
Here are my thoughts about the design:
Inventory - Goods (id, quantity, prices and etc) - Groups
Customer (id,name) - Order(Date) - OrderItem(GoodId, price, quantity)
Operation: Order

In Python, one could use the .create_rpc() method to fire off several
