Applying the Design Thinking Framework, the development follows five phases: Empathize – Understand the needs of doctors, nurses, patients, and administrators. Common requirements include storing personal details, scheduling, billing, and record management. Define – Identify that many entities share similar attributes like name, address, contactNumber, and id. A base class Person can store these common features. Ideate – Plan an inheritance hierarchy: Base Class: Person – Common attributes and methods such as getDetails() and updateContact(). Derived Classes: Doctor – Adds specialization, consultationFee, schedule(). Nurse – Adds assignedWard, shiftTiming. Patient – Adds medicalHistory, admissionDate. Another hierarchy could be MedicalRecord as a base, with subclasses InpatientRecord and OutpatientRecord. Prototype – Develop a small module where these classes interact. For example, a Doctor object can access Person attributes and also perform role-specific functions like prescribing medicine. Test – Validate if code reusability and scalability are achieved. For instance, adding a Surgeon class requires no change in Person but extends Doctor. Benefits: Inheritance minimizes code duplication, ensures maintainability, and supports scalability. The is-a relationship (Doctor is-a Person, Patient is-a Person) keeps the HMS structure organized, fulfilling both technical efficiency and user needs identified in the empathize phase
