Advantages for setting up a restaurant online ordering system include increased income, lower overhead, lower marketing costs, broader customer reach, secure transactions, and increased customer satisfaction. By the completion of this class, you will have developed a Java graphical user interface (GUI) application that supports the “Famous Favorite Subs” online ordering system. This application allows customers to order their favorite sub for delivery.You have learned in a previous class that thoroughly defining requirements and creating a design before you dive into programming is extremely important for developing the application that your customer requested. In this Discussion Board, you are asked to compare and contrast class diagrams, sequence diagrams, and activity diagrams, and to provide an example of each.Research at least 2 sources (which may include your textbook) to support your response.Within the Discussion Board area, respond to the following questions with your thoughts, ideas, diagrams, and comments. This will be the foundation for future discussions by your classmates. Be substantive and clear, and use examples to reinforce your ideas.Complete the following: Compare and contrast class diagrams, sequence diagrams, and activity diagrams by discussing the similarities and differences between each technique, including what design information they are representing. What role does the use case serve in supporting the creation of class diagrams, sequence diagrams, and activity diagrams? Represent the depicted simple ordering system in terms of the class diagrams, sequence diagram(s), and activity diagram(s) for the following use case diagram utilizing a tool such as Visio:
