hi duffymo
i understand it little bit now,but i cannot get yet the table ORDERS will contain the the order id and what else?what will be the other attribute in the table ORDERS?are students so lacking in imagination and thought these days?
imagine yourself getting ready to check out your shopping cart at eBay. if it contained an Order object for that day's shopping, along with one OrderLineItem for every goodie you bought, what else would your system want to know about Order?
Let's see - maybe the date and time on which it was placed would be useful. You'll want to bill someone, so maybe a Person doing the buying, with Address objects for billing and shipping if they differ.
and in the table ORDER_LINE_ITEMS each item,quantity,price row is related to an id like
1,a,5,200
1,b,7,400
2,c,9,500
right?i need little explanation here please?explanation? you sound like you need someone to do all the thinking for you. sorry, i prefer not to do homework for others.
