1. Using the information provided in the scenario described below, create an event table using the following template:

Event | Trigger | Source | Use Case | Response | Destination | | | | | | |

2. A firm caters lunch for its employees. The firm provides a menu that currently has ten food items (which also includes desserts). The menu is maintained by Jill, the coordinator of the social club in the firm. At the beginning of every month, the menu is printed and distributed to employees in the firm.

When an employee wants to order a lunch, the employee ticks off the food items he or she wants on the menu and sends it to Jill. Jill records information about the lunch order i.e. the employee who placed the order, which food items were ordered and the requested date. Lunch orders have to be submitted at least one day in advance. Occasionally, employees might submit a change to their lunch order.

Every evening, Jill looks through the lunch orders for the next day and sends purchase orders to suppliers for the food items requested in those lunch orders. A food item on the menu is supplied by one supplier.

An employee pays for a lunch when it is delivered to the employee. The payment is recorded and a receipt is given to the employee.

At the end of each month, a report that shows the total number of orders for each food item is produced and sent to JillLUNCHES Conceptual Data Model 3.
