Given the following information abo ut a carpool program that uses a system to match up potential drivers with potential passengers, answer the questions below. Entities: passengers (search for drivers based on personal preferences) drivers (post itinerary information) Data store: D1: Passenger files D2: Driver files Processes: 1. Drivers provide itinerary information, which is to be stored at D2 2. Potential passengers can input his/her preference, which is to be stored at D1 3. Match the passenger preference with drivers’ itinerary information 4. A list of potential drivers, as a result of the matching algorithm, will be formatted on the web page, to be seen by the passengers 1) Create a context diagram for the carpool system 2) Draw a logical data flow diagram (Diagram 0)
