Day 6 Check E-Commerce and Transactions

Check yourself

Ten questions on the three designs from Day 6, the shopping cart, the payment gateway and the stock exchange. None of them is a high volume system, yet all three are hard. Each refuses to compromise on something different, and several questions ask you to say what.

You will be asked 10 questions drawn from a larger bank, so a second attempt will not be the same paper. Answer from what the designs actually said, not from what sounds sensible in general.
