Key Features Explained

Productivity Score Calculation

Score = (Completion Rate × 0.6) + (Time Efficiency × 0.4)
- Completion Rate: (Tasks Completed / Tasks Planned) × 100
- Time Efficiency: (Planned Time / Actual Time) × 100

Real-time Updates

WebSocket connection at /ws/tasks/ provides:

• Task status updates
• Productivity log changes
• Activity notifications

Role-Based Access Control

• User: Can manage own tasks and view own analytics
• Admin: Full system access

Database Schema Highlights

• Normalized design with proper foreign keys
• Indexes on frequently queried fields
• Unique constraints where appropriate
• Cascading deletes for data integrity
• Audit logging with ActivityLog model

Security Measures

✅ JWT token-based authentication ✅ Password hashing with Django's built-in system ✅ CSRF protection enabled ✅ CORS properly configured ✅ Input validation and sanitization ✅ SQL injection protection (ORM usage) ✅ XSS protection with React ✅ Rate limiting ready ✅ Secrets management via environment variables

Performance Optimization

• Database query optimization with .select_related() and .prefetch_related()
• Redis caching for frequently accessed data
• Pagination on all list endpoints
• Efficient WebSocket message handling
• Static file compression
• CDN-ready architecture
