Part I. State Machine Diagram Based on the following descriptions of the approval process of a travel authorization form, identify all the states and exit transitions and the draw a behavioral state machine diagram. A travel authorization form is used in most companies to approve travel expenses for employees. Typically, an employee fills out a blank form and sends it to his or her boss for a signature. If the amount is fairly small (<$300), then the boss signs the form and routes it to accounts payable to be input into the accounting system. The system cuts a check that is sent to the employee for the right amount, and after the check is cashed, the form is filed away with the canceled check. If the check is not cashed within 90 days, the travel form expires. When the amount of the travel voucher is a large amount (>$300), then the boss signs the form and sends it to the CFO, along with a paragraph explaining the purpose of the travel; the CFO signs the form and passes it along to accounts payable. Of course, the boss and the CFO can reject the travel authorization form if they do not feel that the expenses are reasonable. In this case, the employee can change the form to include more explanation or decide to pay the expenses. Part II. Data Flow Diagram Create Context Diagram and Level-0 DFD based on the following business scenario. With a patient portal, patients can access their medical records, schedule appointments, and fill prescriptions. Lets look at the medical record function of the patient portal. 1. The system will show a patients medical history such as test results, ongoing health conditions, and immunizations records. 2. If there is an ongoing health conditions, both patient and doctor will receive alert when the alert condition is triggered. Alert conditions are set by doctors. 3. When a physician receives alert, he or she can view and respond to the alert. 4. Patient requests and receives alert data. 5. Physician sends test results to the system and patient can request and access test results. 6. Physician sends and annotates immunization records and patient view immunization records. 7. Patient and physician can exchange messages.
