Draw context diagram and top-level data flow diagram for the group project

To create context and top-level data flow diagrams (DFDs) for the Kenyatta University Teaching, Research, and Referral Hospital, let’s outline their purpose and components first.

Context Diagram

Purpose: A context diagram provides a high-level view of the system and its interactions with external entities. It identifies the system's boundaries and shows how data flows between the system and external actors.

Components:

System: Kenyatta University Teaching, Research, and Referral Hospital
External Entities:
- Patients
- Healthcare Providers
- Insurance Companies
- Regulatory Bodies

          [Regulatory Bodies]

Top-Level Data Flow Diagram

Purpose: The top-level DFD provides a more detailed view of the system, showing the main processes and data stores. It illustrates how data moves within the system.

Components:

Processes:
1. Patient Registration
2. Appointment Scheduling
3. Patient Care Management
4. Billing and Insurance Processing
5. Reporting and Compliance
Data Stores:
- Patient Records
- Appointment Logs
- Billing Information
- Compliance Reports
