## Key Implementation Details
### Database Schema
The implementation created three main database tables:
1. **Detainee** - Stores personal information and identifiers
2. **Facility** - Contains facility information with GPS coordinates
3. **DetaineeLocationHistory** - Tracks detainee movements over time
### API Endpoints
Three main REST endpoints were implemented:
1. `GET /api/facilities` - Returns all facilities with coordinates
2. `GET /api/facility/{id}/current-detainees` - Returns detailed facility information
3. `GET /api/heatmap-data` - Returns aggregated data for visualization
### Frontend Components
Both web and mobile applications include:
1. **Map Visualization** - Interactive maps showing facility locations
2. **Facility List** - Scrollable list with detainee counts
3. **Tab Navigation** - Switching between search and heatmap views
4. **Loading States** - Visual feedback during data fetching
5. **Error Handling** - Graceful handling of API failures
### Performance Optimizations
1. **Caching** - Client-side caching to reduce API calls
2. **Connection Pooling** - Database connection optimization
3. **Efficient Rendering** - Optimized component re-rendering
4. **Lazy Loading** - Deferred loading for non-critical resources
## Testing Coverage
The implementation includes comprehensive testing:
1. **Unit Tests** - Individual function and component testing
2. **Integration Tests** - End-to-end workflow testing
3. **API Tests** - Endpoint response validation
4. **Database Tests** - Data integrity and operation testing
## Deployment Readiness
The implementation is structured for easy deployment:
1. **Modular Architecture** - Separated concerns for independent deployment
2. **Configuration Management** - Environment-specific settings
3. **Containerization Ready** - Docker-compatible structure
4. **CI/CD Pipeline** - Automated testing and deployment scripts
## Future Enhancement Points
1. **Real-time Updates** - WebSocket integration for live data
2. **Advanced Filtering** - More sophisticated search capabilities
3. **Historical Visualization** - Time-based data exploration
4. **Export Functionality** - Data export in multiple formats
5. **Accessibility Improvements** - Enhanced screen reader support
