You are to produce a set of object-oriented models that represent the operations of the taxi service company described below inProblem Scenario. The graphical models are to be produced using a software drawing package such as Microsoft Visio or Microsoft PowerPoint and follow the UML Version 2.0 convention. Also describe the graphical models in plain English so that an independent reader will have a clear understanding of your models.

The specific models you are to produce are:

• Use case description and diagrams for a dispatch call from the dispatcher.
• The activity diagram for the processing of a fare payment by the passenger.
• The sequence diagram for security camera operations.
• The state machine diagram for security camera operations.
• The class diagram for all described elements of the information systems.

You will notice that not all elements of a Functional Requirements Specification have been required in this assignment. That is because the complexity involved in a full specification requires more time than you reasonably would have available to do the work.
