How will the new tables look like?

Answer 1

A foreign key, DoctorID, is added to the PATIENT table, linking it to the DOCTOR table to establish a one-to-many relationship.

Step-by-step explanation:

The foreign key DoctorID will be added to the PATIENT table to establish the one-to-many relationship with the DOCTOR table.After establishing the relationship with a foreign key, the PATIENT table would include the DoctorID field to reference the DOCTOR table. Therefore, the new PATIENT table will look as follows: PATIENT (PatientID, Name, PhoneNumber, Email, Address, DoctorID). The DoctorID in the PATIENT table is a foreign key that references the DoctorID in the DOCTOR table, ensuring that each patient is associated with only one doctor, whereas a doctor can have multiple patients associated

The foreign key in the patient table would be the DoctorID, which refers to the DoctorID in the doctor table. This establishes the one-to-many relationship between the two tables.The new tables would look like this:DOCTOR (DoctorID, Name, PhoneNumber, Email, Office#)PATIENT (PatientID, Name, PhoneNumber, Email, Address, DoctorID)
