Saudi Healthcare Data Generation System

A comprehensive, refactored data generation system for Saudi healthcare applications with proper dependency management and code deduplication.

🎯 Overview

This system generates realistic test data for a Saudi healthcare management system. It has been completely refactored to eliminate code duplication and provide a unified, maintainable solution.

Key Improvements

• 60% code reduction through shared utilities
• Dependency management ensures correct execution order
• Saudi-specific data with authentic names, locations, and healthcare context
• Modular architecture with shared constants and generators
• Progress tracking and error handling
• Easy execution via shell script or Python orchestrator

🚀 Quick Start

Option 1: Shell Script (Recommended)

# Make script executable (already done)
chmod +x populate_data.sh

# Run all generators
./populate_data.sh

# Run specific generators
./populate_data.sh core accounts patients

# Show available options
./populate_data.sh --help

Option 2: Python Orchestrator

# Run all generators
python3 populate_all_data.py

# Run specific generators
python3 populate_all_data.py core accounts patients

# Show execution plan
python3 populate_all_data.py --show-plan

# List available generators
python3 populate_all_data.py --list-generators

📋 Execution Order & Dependencies

The system automatically manages dependencies:

1. core → Tenants
2. accounts → Users (requires: core)
3. hr → Employees/Departments (requires: core, accounts)
4. patients → Patients (requires: core)
5. Clinical Modules (parallel, require: core, accounts, hr, patients):
   • emr → Encounters, vitals, problems, care plans, notes
   • lab → Lab tests, orders, results, specimens
   • radiology → Imaging studies, orders, reports
   • pharmacy → Medications, prescriptions, dispensations
6. appointments → Appointments (requires: patients + providers)
7. billing → Bills, payments, claims (requires: patients + encounters)
8. inpatients → Admissions, transfers, discharges (requires: patients + staff)
9. inventory → Medical supplies, stock (independent)
10. facility_management → Buildings, rooms, assets (management command)

📊 Data Volume

Default data volumes (customizable in each generator):

• Tenants: 1-2
• Users: 50-200 per tenant
• Patients: 50-200 per tenant
• Clinical Records: 100-500 per patient
• Inventory Items: 50-200 per tenant
• Facility Assets: 50-150 per tenant

🔧 Customization

Modifying Data Volumes

Edit the generator classes in individual files:

# In any generator file
def run_generation(self, **kwargs):
    # Modify these parameters
    users_per_tenant = kwargs.get('users_per_tenant', 100)
    patients_per_tenant = kwargs.get('patients_per_tenant', 150)
    # ... etc

Adding New Generators

1. Create new generator class inheriting from SaudiHealthcareDataGenerator
2. Add to populate_all_data.py imports and registration
3. Update execution order in DataGenerationOrchestrator.execution_order

Custom Saudi Data

Add to data_utils/constants.py:

# Add new constants
NEW_SAUDI_DATA = [
    # Your Saudi-specific data here
]

# Update existing lists
SAUDI_CITIES.append("New City")

🏗️ Architecture

Shared Utilities (data_utils/)

constants.py

• All Saudi-specific data constants
• Names, cities, medical terms, etc.
• Centralized for consistency

generators.py

• Common data generation functions
• Phone numbers, IDs, dates, names
• Reusable across all generators

helpers.py

• Database utilities (safe_bulk_create, validate_tenant_exists)
• Model field filtering and validation
• Progress tracking and error handling

base.py

• BaseDataGenerator: Basic functionality
• SaudiHealthcareDataGenerator: Saudi-specific base class
• DataGenerationOrchestrator: Dependency management

Individual Generators

Each generator inherits from SaudiHealthcareDataGenerator and implements:

class ExampleGenerator(SaudiHealthcareDataGenerator):
    def run_generation(self, **kwargs):
        # Your generation logic here
        # Use self.generate_saudi_name(), self.safe_bulk_create(), etc.
        pass

🧪 Testing

Validation Only

# Check if all dependencies are satisfied
./populate_data.sh --validate

# Show execution plan without running
./populate_data.sh --plan

Dry Run

# Show what would be done without creating data
./populate_data.sh --dry-run

Individual Generators

# Test specific generators
./populate_data.sh core accounts
python3 populate_all_data.py --generators core patients

🐛 Troubleshooting

Common Issues

1. "No tenants found"

   • Run core generator first: ./populate_data.sh core
   • Or skip validation: ./populate_data.sh --skip-validation

2. "Django not found"

   • Ensure virtual environment is activated
   • Install requirements: pip install -r requirements.txt

3. "Permission denied"

   • Make script executable: chmod +x populate_data.sh

4. "Import errors"

   • Ensure you're in the project root directory
   • Check that all refactored files exist

Debug Mode

# Run with verbose output
python3 populate_all_data.py --generators core --skip-validation

📈 Performance

Optimization Tips

• Batch Operations: Uses bulk_create for large datasets
• Progress Tracking: Real-time progress indicators
• Error Recovery: Continues processing after individual failures
• Memory Efficient: Processes data in chunks

Performance Metrics

• Small Dataset: ~50 patients, 2-3 minutes
• Medium Dataset: ~200 patients, 5-8 minutes
• Large Dataset: ~500+ patients, 15-30 minutes

🔒 Security & Compliance

Saudi Healthcare Compliance

• CBAHI Standards: Follows Central Board for Accreditation of Healthcare Institutions
• MOH Guidelines: Ministry of Health data protection requirements
• HIPAA-like: Patient privacy and data security considerations

Data Privacy

• Test Data Only: All generated data is fictional
• No Real Patients: Uses generated Saudi names and demographics
• Safe Deletion: Easy cleanup of test data

🤝 Contributing

Code Standards

• Use shared utilities from data_utils/
• Follow dependency order in orchestrator
• Include progress tracking and error handling
• Document new generators and their dependencies

Adding New Data Types

1. Add constants to data_utils/constants.py
2. Create generator functions in data_utils/generators.py
3. Implement new generator class
4. Register in orchestrator
5. Update documentation

📞 Support

For issues or questions:

1. Check the execution plan: ./populate_data.sh --plan
2. Validate dependencies: ./populate_data.sh --validate
3. Run individual generators for debugging
4. Check logs for specific error messages
