SQL - Transactions and Data Integrity

A bank application uses SERIALIZABLE isolation level to prevent anomalies. However, users report frequent transaction failures due to serialization errors. What is the best approach to reduce these errors while maintaining data accuracy?

AKeep SERIALIZABLE and retry failed transactions automatically

BDisable transactions to improve performance

CSwitch to READ UNCOMMITTED to avoid errors

DLower isolation level to READ COMMITTED and add explicit locking where needed

Step-by-Step Solution

Solution:

Step 1: Understand SERIALIZABLE issues and evaluate best practice
SERIALIZABLE prevents anomalies but causes serialization errors on conflicts. Lowering isolation risks anomalies; best is to keep SERIALIZABLE and retry failed transactions automatically.
Final Answer:
Keep SERIALIZABLE and retry failed transactions automatically -> Option A
Quick Check:
Retry on serialization errors = Keep SERIALIZABLE and retry failed transactions automatically [OK]

Quick Trick: Retry failed SERIALIZABLE transactions to keep accuracy [OK]

Common Mistakes:

Lowering isolation level without safeguards
Ignoring serialization errors
Disabling transactions for performance
