Good evening, my friend. I have this task that one of the teachers solved, but he asked to change the values so that there is no similarity. Can you do that?

Outcome(s):
Hospital Management System
Year 2030, you are hired as a database developer in local hospital. The top
management of the hospital is interested to design a new database to manage their
daily routine work. In the requirement identification phase, you have identified five
core elements in the hospital

schemas.
•
Patients: The hospital stores crucial patient data, including their
personal information (first name, last name, date of birth, gender), contact
details (phone number, address), insurance information, and their medical
history.
•
Doctors: Hospital also maintains records of the medical
professionals, including their specialization, contact information, license
number, office hours, and email addresses.
•
Appointments: For efficient management of the patients visits to
the hospitals, the data about each appointment is stores as it connects

patients with specific doctors. The appointment date and time, the reason

completed) is also stored.
•
Medical Records: A comprehensive record of patients’ medical
histories is maintained. It includes diagnosis details, treatment plans,
prescriptions, test results, and the date of each medical visit. These records
are associated with both patients and doctors.
•
Medical Staff: Data related to hospital staff members, such as
nurses, receptionists, and administrators is also stored. Information like
their roles, contact details, shift timings, and salary is recorded for proper
staff management.

Explanation:
•
Treats: A doctor can treat many patients, also, many patients may be treated by
many different doctors in the same hospital.
•
Schedules: A doctor manages his appointment(s) times and dates for each
patient, and each appointment can only have one doctor in the appointment.
•
Attends: A patient can have multiple appointments he must attend to, but each
appointment is for one patient only.
Hospital Management System
Pg. 06
•
Manages_Records: A doctor can manage the overall medical record of many
patients that he treats, moreover, the same medical record can be managed by
many doctors, as the patient may be getting treatment from many different
doctors (such as in Treats relationship type)
•
Owns_Record: Each single patient in the hospital has ONE medical record that
has all the details of the patient medical history, and each medical record is
associated with only ONE patient.
•
Manages: Each doctor has ONE administrative manager that is responsible for
the Doctor, contacts, salary, personal clinic and his work related documents. A
Medical_Staff can manage MANY Doctors at a time.

Step 1: 1NF
We must map the multivalued attribute into a relation of its own.
Medical_Record
Record_ID (Primary Key)
Record_ID (Primary Key)
Patient_ID (Foregin Key)
Diagnosis_details
Treatment_plans
Prescriptions
Test_results
Visit_Dates
Record_ID (Primary Key + Foreign Key)
Date_of_each_visit (Primary Key)
Record_ID (Primary Key + Foreign
Key)
Date_of_each_visit (Primary Key)
Step 2: 2NF
Relation already in 2NF because no partial functional dependency exists, as in, no nonkey (non-prime) attribute is determined by a subkey (part of primary key). Hint: If we
have non-composite primary key (There is only one attribute that is a primary
key), we can NEVER have a partial functional dependency.
Hospital Management System
Pg. 12
Step 3: 3NF
To be in 3NF, no nonprime attribute of R is transitively dependent on the primary key,
as in it has no transitive dependencies. In other words, No non-key attribute determines
another non-key attribute. This is violated in the following transitive dependency:
Record_ID -> Patient_ID -> { Diagnosis_details, Treatment_plans, Prescriptions,
Test_results, Medical_history}
To solve this, we remove the dependent attributes from the relation and move these
attributes ({ Diagnosis_details, Treatment_plans, Prescriptions, Test_results,
Medical_history}) to a separate table with its determinant (Patient_ID) and keep the
determinant (Patient_ID) in the relation as a foreign key

3) List of all the Patients who have not paid their bills till today.
4) List of Doctors on leave in a particular month.
5) List of Appointments with each Doctor with Patient name for a particular
day.

ASSUME there is bill_paid column in Patient table, this will be the query.
However, this query will give an error because there is no bill_paid field.
ASSUME there is on_leave column nor leave_month in Doctor table, this will be
the query. However, this query will give an error because there is no on_leave
column nor leave_month field.
