Objectives: 1. Development of static model for requirements analysis 2. Development of dynamic model for requirements analysis

The use case description for the check-in patient is given below. Provide your answers to the following questions. Use a UML tool when you draw diagrams. Hand drawn diagrams may not be grades.

a) Identify classes for the check-in patient use case. A class can be classified as an interface class, entity class, control class, or application logic class. Describe each class as to what it does or why it is needed. Define the attributes of each entity class and describe each attribute shortly. (10 pts)

b) Develop the communication diagram or sequence diagram that depicts objects participating in the check-in patient use case and the sequence of interactions among the objects. A successful scenario (main sequence) and alternative scenarios (alternative sequences) in the check-in patient use case must be depicted on different communication diagrams or sequence diagrams. (20 pts)

The use case description for the check-in patient use case in healthcare system is:

Name: Check-in patient

Summary: The staff checks in a patient to the system.

Actors: Staff, Health Insurance

Pre-conditions: None

Description: 1. The staff checks if a patient has an appointment. 2. If the patient has an appointment, the staff enters or updates patient information to the system, which include patient name, address, phone number, social security number and health insurance. 3. System sends the patients health insurance information to the health insurance. If the health insurance approves the patients doctor visit, the health insurance confirmation number is created and sent back to the healthcare system. 4. System adds the patient name to a list of patients being served by a doctor. Alternatives: If the system cannot find the patients appointment, the staff cancels check-in. If the health insurance denies the patients doctor visit request and patient does not want to pay all cost, the staff cancels check-in. If the health insurance denies and the patient wants to pay all cost, staff adds the patient name to a list of patients being served by a doctor.

Post-conditions: The staff has checked in a patient. State your assumptions if necessary.
