A company called Street Order Ltd manages street parking in Kampala city. The company collects revenue by charging any vehicle that park on streets of the city. Government vehicles are charged at a half rate per hour and diplomatic vehicles are charged at a quarter rate per hour. All other vehicles (ordinary) are charged at full rate F per hour. The value of the rate F may be changed at any time. An invoice is issued by a parking attendant (who is managing that specific street) to a parked vehicle and the owner settles the invoice by issuing the required number of tickets to the parking attendant. However, the car owner is at liberty to settle the invoice at a later time but a penalty of P% of the invoice value will be charged every D days. The value of P and D may be changed any time. When settlements are done later, the owner of the vehicle takes the required number of tickets or equivalent cash to the cashier based at the company office. Parking tickets are sold by ticket vendors. A certain percentage K of the monthly revenue collected by Street Order Ltd is paid to Kampala city council and a percentage M to the Ministry of Works. The Company keeps the balance. The values of K and M may be changed any time. The Company operates a bank account where all cash collections are deposited and withdraws are made to meet various business obligations. You are contracted by the company to develop a database system that can be used by management to:

1. Monitor the number of tickets sold per month and therefore get the total monthly income. The system should also show the income from ordinary vehicles, government vehicles and diplomatic vehicles.

2. Monitor detailed and consolidated information about unsettled invoice including accumulated penalities attendant and cashiers.

3. Monitor the monies due Kampala city council and the Ministry of Works.
