Database Audit Logging for Transaction Monitoring

Abstract

Database audit logging is an important practice for transaction monitoring in enterprise systems where financial entries, user actions, data updates, approvals, and security-related events must be recorded accurately. In business applications, weak audit logging can make it difficult to trace unauthorized changes, investigate transaction errors, verify user activity, and support compliance requirements. This article discusses how structured audit logging helps monitor database transactions by capturing user identity, timestamp, operation type, affected table, old and new values, transaction status, and source application details. It explains the role of audit tables, triggers, log retention policies, access control, exception tracking, and review reports in improving transaction visibility. The article also highlights common challenges such as excessive log volume, incomplete audit trails, performance overhead, unclear retention rules, and poor monitoring of privileged users. A structured audit logging approach is presented to improve accountability, support fraud detection, strengthen compliance, and protect database integrity. The study concludes that effective database audit logging improves transaction transparency, supports reliable monitoring, and enhances governance of enterprise database systems.
