Introduction

You have been hired by the agency that runs the state lottery to design a strategy for managing the interaction between the lottery's central office and the "lottery terminals" in stores throughout the state. Your task in this assignment is to write a memo describing your proposed design, and discussing how well your design meets the criteria set out below. You will be graded partly on your design, and partly on your analysis and critique of your own design.
How the Lottery Works

Lottery tickets are sold for $1 each and can be bought from lottery terminals that are placed in convenience stores throughout the state. Each lottery ticket must have at least three things printed on it: the identity of the terminal that printed it, a timestamp (of up to 1 millisecond accuracy) that marks when it was printed, and a "lucky number" which is an integer between 0 and 9,999,999 inclusive. You may add additional information to each ticket. Lottery tickets go on sale at 8:00 AM every Monday, and can be bough
