Hospital Management System (UML Diagrams)
Hospital management systems are complex and involve various stakeholders, processes, and data flows. UML diagrams are especially helpful for these systems to visualize and design the particular modules and interactions. They help in understanding, documenting, and communicating the structure and behavior of the system.
Hospital Management System Diagrams
This article presents a comprehensive set of UML diagrams for a hospital management system, including use case, class, and sequence diagrams. Each diagram serves a specific purpose:
- Use Case Diagram: Illustrates the interactions between actors (e.g., doctors, patients) and the system, detailing actions such as patient registration, examination, and discharge processes. You can find step by step tutorial (including video) on how to work with the use case diagram here: How to Create a Use Case Diagram: A Step-by-Step Guide
- Class Diagram: Depicts the static structure of the system, showing classes like Doctor, Patient, and Diagnosis, along with their relationships and attributes. A detailed, step-by-step tutorial (including video) on working with the class diagram is available here: How to Create a UML Class Diagram
- Sequence Diagrams: Visualize dynamic behavior, demonstrating the sequence of interactions, such as a doctor's visit or patient examination, highlighting the communication between system components. For a comprehensive guide on how to use the sequence diagram, click here for the full tutorial (including video): How to Create a UML Sequence Diagram
These diagrams collectively provide a detailed blueprint of the hospital management system, facilitating efficient system design and implementation.
UML Use Case Diagram
The use case diagram for the hospital management system shows the actors:
- Doctor
- Patient
and their defined use cases:
- Doctor
- Visit the patient
- Examine the patient
- Add diagnoses
- Prescribe drugs
- Schedule the medical procedure
- Discharge the patient
- Report the patient condition
- Patient
- Register
- Unregister
- Apply for discharge
- Confirm the medical procedure
UML Class Diagram for Hospital Management System
The class diagram depicts the classes, an association class, and enumerations that are used within the modeled hospital management system.
Classes:
- Nurse
- Employee
- Doctor
- Patient
- Technical Staff
- Receptionist
- Diagnosis
- Diagnosis Type
- Schedule
- Schedule Time
- Action
- Allowed Actions
- Specialization
- Symptom
- Room
- Request Form
- Patient History
- Administered Drug
- Drug
- Diagnosis Type Symptom
Enumerations:
- Occurrence
- Patient Status
- Action Type
- Request Type
UML Class Diagram of Hospital Rooms
The diagram describes a class hierarchy of hospital rooms and other associated classes.
These classes are defined in the diagram:
UML Sequence Diagram of Doctor's Visit
The UML sequence diagram example shows a doctor's visit and a check of a patient.
The diagram depicts these lifelines:
- Doctor
- Patient
- Hospital System
The following messages occur between the lifelines:
- Confirm visit
- Check schedule
- Patient visit planned
- Check the patient condition
- Report patient condition
UML Sequence Diagram of Patient Examination
The sequence diagram shows a patient examination by a doctor.
There are these lifelines:
- Doctor
- Patient
- Hospital System
The lifelines communicate with the following messages:
- Start the examination
- Add symptom
- Show recommended diagnoses
- Add the diagnosis
- Prescribe the needed drug
- Show found contraindications
- Propose the medical procedure
- Confirm the medical procedure
- Show possible dates
- Choose a date
- Confirm the schedule
