Core java assignment patient with a doctor 67854_Scenario1

NemCare is a leading health care provider in the US and has multispecialty hospitals in seven cities nationwide. In its effort to reach out to people who do not have access to medical facilities, NemCare has decided to operate Out Patient Clinics. Each NemCare clinic will have a qualified medical team that provides consultations to patients visiting the clinic. NemCare has already started work to make two clinics operational within six months. Having realized the need to automate the operations of the clinics, the management of NemCare has hired ProDev, an IT consultancy firm, to design and automate the processes common to each clinic. In the first phase, NemCare has assigned ProDev to create Patient Management System (PMS). 
You have been assigned to lead a team to design and develop PMS. Based on the initial requirement, you have documented that each clinic will initially have the following departments with more departments likely to be added in a phased manner:
 General Medicine  Cardiology  Neurology  Gastroenterology 
Each department will have a team of doctors with different consultancy timings. 
In subsequent meetings, you have gathered the requirements of PMS. Initially, PMS will be a single user application that allows an employee of a clinic to register a new patient visiting the clinic and generate a unique patient ID for the patient. The clinic will provide a printed registration card to the patient. During subsequent visits to the clinic, the patient will be required to provide the registration card for appointments or any other transactions.
The system should allow an employee to create an appointment for a registered patient with a doctor. The system should create a unique appointment file for each patient that will be updated when the patient revisits the clinic. Each appointment file should be stored categorically by the departments of the clinic. For a revisiting patient, the system should allow an employee to view the appointment file of the patient.     Being the team leader at ProDev, you have been assigned the task of analyzing the scenario and lead the team in creating PMS.
