i am working on a mobile service. Help me by showing me the use case diagram, the class diagram and the sequence diagram. The system / service is such that the owner of a vehicle can receive an SMS from his vehicle when either the window is broken or the door is opened or ....(sensors). and then the owner can lock the engine. he also should be able to track his vehicle if stolen (changed position,GPS) by his phone....the system also should be able to tell the nearby pedestrian that this vehicle is a stolen one!.......the system should also be able to send the SMS to the owner's freind incase the owner can not handle the SMS sent by the system on the vehicle.......the owner should also be able to send help message to the police department through the system if he wants so that the police can also track the stolen vehicle.
Thank you.
