This exercise has two parts (1) ER-Modelling and (2) Sequence Diagramming. Submit a single PDF document containing both diagrams. Consider the following description of a traffic law enforcement information system: Police officers on patrol may stop drivers and ask for their drivers license and insurance papers. Officers can use mobile computers installed in their vehicles to check whether there is a search warrant on the driver or whether the driven car is considered stolen or missing. The server at the police head quarter can also contact ICBC to validate that the insurance is current and the drivers license is valid. Police officers have to authenticate with a password before they can use the system. The system can also be used to issue a ticket for a traffic law infringement. The police officer's vehicle has a small printer to print the ticket. 1) Create an ER-model for this system. 2) Create a sequence diagram for a typical traffic patrol scenario This exercise has two parts (1) ER-Modelling and (2) Sequence Diagramming.
