ERP Integration Points

1. Authentication & User Management Integration

Single Sign-On (SSO): Logistics module inherits ERP's authentication system
Role-Based Access Control (RBAC): Uses ERP's existing user roles and permissions
User Context: Inherits user profile, department, and authorization levels
Session Management: Shared session handling across ERP modules

2. Database Integration

Shared Oracle Database: Logistics tables reside in the same database as core ERP
Referential Integrity: Foreign key relationships with ERP core tables
Transaction Management: Participates in ERP-wide distributed transactions
Backup & Recovery: Included in ERP's backup and disaster recovery procedures

3. API Integration

Unified API Gateway: All requests go through ERP's API gateway
Namespace Isolation: Logistics endpoints under /api/v1/logistics/
Shared Middleware: Authentication, logging, rate limiting, and monitoring
Cross-Module Communication: Inter-module communication for project data

4. User Interface Integration

Embedded Module: Logistics UI integrated within ERP's main interface
Consistent UI/UX: Follows ERP's design system and user experience patterns
Navigation Integration: Accessible through ERP's main navigation menu
Shared Components: Uses ERP's common UI components and styling

5. Business Process Integration

Workflow Engine: Leverages ERP's workflow engine for approvals
Notification System: Uses ERP's notification infrastructure
Audit Trail: Integrated with ERP's audit logging system
Reporting Integration: Logistics reports available through ERP's reporting module

6. Data Synchronization Points

Project Data: Real-time synchronization with ERP project management
User Data: Automatic updates when users/roles change in ERP
Financial Data: Integration with ERP accounting for invoicing and payments
Vendor Data: Synchronization with ERP vendor/supplier management
