Schema 1 COVID-19 clinic: (50) Mass General Hospital runs a collection of COVID-19 clinics throughout the city of Boston. A clinic has many staff members who work at it. A staff member has a name, an employee number, (empNo) which is unique, as well as a job description. A staff member may only work at one clinic. Each clinic has a unique clinic number (clinicNo) and an address, The clinic has a store of vaccines that are available for injection. Each vaccine instance has a vaccine type and a unique VaccineID, which is a unique number for the vaccine type. Currently there are two vaccine types approved in the US, the Pfizer and the Moderna vaccine type. For each vaccine type the clinic must track the number of injections needed for immunization and the time interval (number of recommended days) between the injections. When a citizen is required to receive a COVID-19 vaccine, he/she contacts a clinic to schedule an appointment. The appointments are an hour in length and can be scheduled from 8AM-8PM on Monday through Friday for a specific day of the year. Each appointment has a unique appointmentId. At the appointment, a citizen is administered the vaccine and is then monitored for a 12 hour by a staff member for side effects. The side effects are: allergic reaction, swelling at the point of injection, stiffness at the point of injection, joint stiffness, fever and headache. After the monitoring stage, the patient is then required to monitor him/herself and to contact the clinic if he/she experiences any side effects. The patient is also required to contact the clinic for any further innoculations needed for the vaccine type that has been administered
