A) Think about sending a first-class letter to an international pen pal. Describe the processthat the letter goes through to get from your initial creation of the letter to being read byyour friend, from the letter's perspective. Draw a behavioral state machine that depicts thestates that the letter moves through.B) Draw a behavioral state machine that describes the various states that a travelauthorization can have through its approval process. A travel authorization form is usedin most companies to approve travel expenses for employees. Typically, an employeefills out a blank form and sends it to his or her boss for a signature. If the amount is fairlysmall ($300), then the boss signs the form andsends it to the CFO, along with a paragraph explaining the purpose of the travel; the CFOsigns the form and passes it along to accounts payable. Of course, the boss and the CFOcan reject the travel authorization form if they do not feel that the expenses arereasonable. In this case, the employee can change the form to include more explanationor decide to pay the expenses.C) Think about the system that handles student admissions at your university. The primaryfunction of the system should be able to track a student from the request for informationthrough the admissions process until the student is either admitted to the school orrejected.1. Write a use-case description that can describe an Admit Student use case.Assume that applicants who are children of alumni are handled differently from otherapplicants. Also, assume that a generic Update Student Information use case is availablefor your system to use.2. Create a use-case diagram that includes all of the above use cases.Assume that an admissions form includes the contents of the form, SAT information, andreferences. Additional information is captured about children of alumni, such as theirparent's graduation year, contact information, and college major.3. Create a class diagram for the use cases identified with questions 1 and 2. Also, besure to include the above information.Assume that a temporary student object is used by the system to hold information aboutpeople before they send in an admission form. After the form is sent in, these people areconsidered students.4. Create sequence diagrams for the scenarios of the above use cases.5. Create a communication diagram for the scenarios of the above use cases.6. Create a behavioral state machine to depict a person as he or she moves through theadmissions process.7. Perform a CRUDE analysis to show the interactivity of the objects in the system
