Q1. ABC is a network of Hospitals. Its having Hospitals across the World. Its possible to take appointment for any Doctor for an available slot on an available date through its website. Its having a Chatbot also. There are many specialities in each of its Hosptitals. However, not all specialities are available across all its Hospitals. Doctors may provide consultancy services in more than one hospital of its network. Its possible to make payment of consultation fee online while taking appointment or directly at hospital prior to consultation. Make assumptions, wherever necessary. Also, list them very clearly. Now, with reference to the above, answer the following:
- (1)) List the Entities (250 words)
- (2)) For each Entity, list Attributes (250 words)
- (3)) Define relationships between the Entities (250 words)
- (4)) Finally, draw the Entity Relationship Diagram (Diagram/N/A)
Key Points:
- Entities: Hospital, Doctor, Patient, Speciality, Doctor_Speciality_Hospital, Availability, Appointment, Payment.
- Doctor_Speciality_Hospital resolves Doctor-Speciality-Hospital many-to-many complexities.
- Availability entity tracks doctor's scheduled time slots for specific DSH combinations.
- Appointment links Patient to an Availability slot, capturing booking details.
Answer: To design a robust database for ABC Hospitals, an Entity-Relationship (ER) model is crucial. This model visually represents the relationships between different data components, known as entities, and their properties, or attributes. Based on the provided scenario, we will identify the key entities involved, define their characteristics, and establish the logical connections between them. Assumptions are made to clarify ambiguities and ensure a comprehensive design. Our primary goal is to create...
