Problem :
The backend/database/db_connection.py (lines 37-68) lacks transaction support, meaning multi-step database operations can leave the system in an inconsistent state if any intermediate step fails.
Scenario 1: File Creation with Metadata Loss
- File created in storage
- Permission record creation FAILS
→ Result: File exists but has no access control
Scenario 2: File Deletion with Audit Trail Loss
- File deleted from storage
- Audit log insert FAILS
→ Result: No record of deletion, compliance violations
Scenario 3: Permission Grant with Encryption Desync
- Permission updated in DB
- Encryption key update FAILS
→ Result: User can't access encrypted data with new permissions
Current Implementation Issues :
No rollback mechanism for failed operations
No atomic guarantees for multi-step processes
No isolation levels for concurrent operations
No constraint violations checking
Expected Behavior :
All multi-step database operations should be atomic , either all steps succeed or all are rolled back to the initial state.
