Statistics​

GET    /api/organisations/stats              # Organization statistics

📈 Performance Characteristics​

Scalability Tested​

  • ✅ Large Organizations: 100+ users per organization
  • ✅ Multiple Memberships: 50+ organizations per user
  • ✅ Concurrent Operations: Thread-safe session management
  • ✅ Memory Efficiency: Optimized for minimal memory usage

Caching Strategy​

  • Session-based caching for user organizations
  • Lazy loading for organization details
  • Manual cache invalidation when needed
  • Database query optimization with indexed lookups

🔐 Security Features​

Access Control​

✅ Organization Isolation: Complete data separation ✅ Permission Validation: All operations validate membership ✅ Cross-Organization Prevention: Blocked access across boundaries ✅ Input Sanitization: SQL injection protection

Tested Security Scenarios​

  • Unauthenticated request handling
  • Malformed JSON request processing
  • SQL injection attempt prevention
  • Unicode and special character support
  • Very long input validation

🗄️ Database Schema​

Organization Entity​

CREATE TABLE openregister_organisations (
    id INT PRIMARY KEY AUTO_INCREMENT,
    uuid VARCHAR(255) UNIQUE NOT NULL,
    name VARCHAR(255) NOT NULL,
    description TEXT,
    users JSON,                    -- User membership list
    isDefault BOOLEAN DEFAULT FALSE,  -- Default organization flag
    owner VARCHAR(255) NOT NULL,   -- Organization owner
