Requirements:

1. Construct a UML diagram that provides a conceptual overview for the data described in the scenario below. No need to include any classes that are not described in the simplified example. .

2. Construct a set of Data Tables that could be used to collect data described in the scenario below. Each data table should have at least three columns (you can make up attributes) and at least three rows (you can made up data records). No need to include any tables that are not described in the simplified example.
Jack Skellington is a proud parent of three “Trick-or-Treat” aged children. Jack is also a CPA and looks for any opportunity to use their Accounting Information Systems knowledge on a new problem. This year Jack hopes to construct a database to record Halloween candy collected. The Skellington family hopes to use the database to optimize routes on future Halloween nights. The database should record of each individual “Trick-or-Treat” event that takes place. The system should work as follows:
O Think of each time someone says “Trick-or-Treat” as an individual transaction. You can even pretend that a receipt is given (Jack is a CPA after all…) that lists the following information. A “Trick-or-Treat” event listed in the database involves a single child.
O A “Trick-or- Treat” event must be associated with a child to be added to the database. Each child will “Trick-or-Treat” many times. A child can be added to the database without a “Trick-or-Treat” event.
O A “Trick-or-Treat” event must take place at a specific location. A “Trick-or-Treat” event must be associated with a location to be added to the database. location can be the site of multiple “Trick-or-Treat” events. A location can be added to the database without a “Trick-or-Treat” event.
O A “Trick-or-Treat” event can result in many pieces of candy. Unfortunately, not all “Trick-or-Treat” events are associated with candy. Some houses are mean and give out toothbrushes or other non-candy items. Non-candy items are considered tricks and NOT recorded in the database. Each candy can be involved in multiple “Trick-or- Treat” events. Candy can be added to the database without a “Trick-or-Treat” event.

Handi Inc., a maker of cellphones, procures a standard display from LCD Inc. via an options contract. At the start of quarter 1 (Q1) Handi pays LCD $3.5 per option. At that time Handi’s forecast of demand in Q2 is Normally distributed with mean 24000 and standard deviation 6000. At the start of Q2 Handi learns exact demand for Q2 and then exercises options at a fee of $4.5 per option (for every exercised option LCD delivers one display to Handi). Assume Handi starts with no display inventory, and displays owned at the end of Q2 are worthless. Should Handi’s demand in Q2 be larger than the number of options held, Handi purchases additional displays on the spot market at $12.5 per unit. For example, suppose Handi purchases 30000 options at the start of Q1 but at the start of Q2 Handi realizes that demand is 35000 units. Then Handi exercises all of its options and purchases 5000 additional units on the spot market. If, on the other hand, Handi realized demand is 27000 units, then Handi only exercises 27000 options. A) If Handi chooses to purchase 20,000 options, what is the probability that Handi needs to purchase displays from the spot market? B) If Handi prefers to have only a 5 percent chance of purchasing displays from the spot market, how many options should Handi purchase at the start of Q1? C) Suppose the price for the display on the spot market changes to $8 per unit, how many options should Handi purchase from LCD at the start of Q1 to maximize the profit?
