1. The student organization, Math and Computer Science Club (MACS), organizes multiple meetings for its members every year, and it would like to develop an application to support the organizational processes needed to ensure the success of these meetings. Each of the meetings will have 5 to 25 participants (sometimes even more), and each meeting takes place in a specific hotel in a specific city in a specific state. The organizers need to know each participant's full name, cell phone number, and email address. MACS wants to maintain information regarding dietary restrictions for each participant at the general level, but the restrictions also need to be confirmed and recorded separately for each meeting. For each member's participation for a specific meeting, the officers need to know how he or she will travel to the meeting, and when he or she is planning to arrive and leave. It is important that MACS can produced an accurate report on how many meetings have been organized in a specific location (place of business) and city.

2. The city of Dallas is looking to expand the number of days that events are held on the square. Fridays after Five during the summer have become very popular and the Saturday special events such as the Grease Festival and Car shows are increasing with attendees every year. Due to this the city has identified a location near the square where a parking garage will be built. The parking garage will service both monthly customers, who pay a fixed fee every month, and visitors, who pay an hourly fee (assume that the hourly fee is the same regardless of the day or time of day). Each monthly customer gets an ID assigned by the garage, and the garage wants to maintain the customer's basic contact information. The monthly fee paid is negotiated separately for each customer, and it changes periodically; it is important the garage to maintain a history of the fee details for each customer. The garage has more than 700 parking spots, each of which is equipped with a sensors that recognizes whether there is a car in the spot; in addition, the sensor can read each monthly customer's customer ID card with an RFID reader and, thus, knows which monthly visitor has parked at which spot and when. Each spot is also equipped with a camera that is able to take a picture of each visitor's license plate number; this information is stored to help locate any vehicle that an owner has misplaced. The system should keep track of each time a parking spot is used, including an image of the license plate, start and end times, and a link to the monthly customer, if appropriate.
