Today, we're going to guide you through creating a Class diagram for a Hospital Management System.

Start by launching app.gleek.io in your browser and ensure you're logged in. Hit 'New Diagram,' choose 'Class diagram' from the dropdown, and let's get started.

First, we'll add the "Patient" class. Just type "Patient" and it will appear on your chart. Now, to add attributes, go to a new line, press "Tab", and write the first attribute: "Name".

After entering the first attribute, press "Enter" to continue adding more:
"Age", "Gender", "Address", "Phone", "Email".

Perfect, and now, let's add methods to the "Patient" class. Press "Enter" on a new line and write method names like "MedicalHistory" and "BookAppointment". Don't forget to add two brackets at the end of each method.

Let's move to the "Doctor" class. Type "Doctor" to create the class. Add attributes like "Name" by following the same tabbing method. Then press Enter and add the rest attributes: "Specialization", and "ContactInfo".
Also, add methods "ScheduleAppointment" and "CheckPatientHistory" to handle doctor operations.

Next, let's move to the "Appointment" class. Type "Appointment" to create the class. Add attributes like "Date", "Time", "Patient Name", and "Doctor Name".
Also, add methods "Create" and "Cancel" to handle appointment operations.

Now, create the "MedicalRecord" class. Type "Medical Record", and add attributes such as "Patient Name", "Doctor Name", "Diagnosis", "Prescription", and "Test Results" using the TAB method.

Include a method called "Update" to update the records, added in the same way as other methods.

Next, add the "Billing" class by typing "Billing". Press Enter, then Tab, and input the first attribute - "PatientName".Add the rest attributes: "DoctorName", "AppointmentDate", and "TotalAmount".

The method "GenerateBill" should also be added using Enter, essential for generating bills for services.

As hospitals are central to the system, type "Hospital" and add attributes like "Name", "Address", and "Contact Info" to represent hospital details.

Now, let's add methods to the "Hospital" class to manage its operations effectively. Press "Enter" to go to the new line and add method names such as "ListDoctors", "ListPatients", "ManageAppointments", and "ManageBilling()". These methods will help in listing all doctors and patients, as well as managing appointments and billing within the hospital.

Now that we have all our classes, attributes, and methods, we need to define the relationships between them.

To show that a patient can have multiple appointments, type "Patient, curvy bracket, one, curvy bracket, dash, curvy bracket, one, two dots, asterisk, curvy bracket, dash, arrow. Then type "Appointment". This indicates that each patient can schedule multiple appointments, which is essential for tracking all visits a patient makes to the hospital.

Next, to show that each appointment is linked to a single medical record, type Appointment, curvy bracket, one, curvy bracket, dash, curvy bracket, one, curvy bracket, dash, arrow. Then type "MedicalRecord". This relationship signifies that during each appointment, a patient's medical record may be reviewed or updated.

To indicate that each patient has one medical record, type "Patient, and then the same one-to-one multiplicity arrow as in the Appointment to MedicalRecord relationship. When the arrow is in place, connect it to "MedicalRecord". This connection shows that a medical record is a comprehensive document that chronicles a patient's health history and treatments.

To represent that each appointment results in billing, type Appointment, and the same arrow we used in the previous connection, then type Billing. This relationship ensures that every medical service provided during an appointment is billed accordingly.

To demonstrate the hospital's overarching role, we need to create aggregation relationships. To show that the hospital encompasses patients in Gleek notation, type Hospital, dash, dash, angle bracket, and close it with an opposite angle bracket to create a diamond shape. Then type Patient. For connecting Hospital to Doctor, type "Hospital, same aggregation arrow, then connect it to Doctor. For Billing, type Hospital, add aggregation relationship, and then type Billing. These aggregations indicate that the hospital encompasses a wide range of operations and services, including managing patient care, doctor staffing, and financial transactions.

And there you have it! Our Hospital Management System class diagram is complete. Explore Gleek's new diagram types like Gantt chart, State, and User Journey diagrams, and share your thoughts with us in the comments.
