Database design for financial systems: integrity, performance and auditability

1Introduction

Design errors cause reconciliation gaps, data loss or audit failures.

2Discussion

Normalisation prevents inconsistency; ACID guarantees all-or-nothing transactions; store money as exact decimals or integer minor units, never floats.

Record changes as new entries with an audit trail rather than editing or deleting; double-entry design keeps balances consistent.

3Conclusion

Targeted indexing, separating historical data and tested backups ensure performance and resilience.
