The clock shows the time of day. Using buttons, the user can set the hours and minutes fields individually and choose between 12 and 24-hour display. It is possible to set one or two alarms. When an alarm fires, it will sound some noise. ‘The user can turn it off or choose to “snooze”. If the user does not respond at all, the alarm will turn off itself after 2 minutes. "Snoozing’ means to turn off the sound, but the alarm will fire again after some minutes of delay. Th time’ is pre-adjustable. Identify the top-level functional requirement for the clock, and model it with a use case diagram Patient Record and Scheduling System A patient record and scheduling system in a doctors office is used by the receptionists, nurses, and doctors. The receptionists use the system to enter new patient information when first-time patients visit the doctor. They also schedule all appointments. The nurses use the system to keep track of the results of each visit including diagnosis and medications. For each visit, free form text fields are used captures information on diagnosis and treatment. Multiple medications may be prescribed uring each visit. The nurses can also access the information to print out a history of patient visits. The doctors primarily use the system to view patient history. The doctors may enter some patient treatment information and prescriptions occasionally, but most frequently they le the nurses enter this information. Each patent i assigned to a family. The head of family s responsible for the person with the primary medical coverage. Information about doctors is maintained since a family has a primary care physician, but diferent doctors may be the ones seeing the patient during the visit. Create a use case diagram for this problem statement. UML Browser-based training Example Let's imagine we will develop a browser-based training system to help people prepare for such a certification exam. A user can request a quiz for the system. The system picks a set of questions from its database, and compose them together to make a quiz. It rates the user's answers, and gives ints if the user requests i In addition to users, we also have tutors who provide questions and hints. And also examinators. ‘who must certify questions to make sure they are not too trivial, and that they are Make a use case diagram to model this system.
