Data must be classified, tracked, and verifiable.

1. Classification

Before storing any field, tag it:

  • Public: Safe to release (e.g., Product Descriptions).
  • Internal: Employee-only (e.g., Org Charts).
  • Confidential: Business secrets (e.g., Sales Forecasts).
  • Restricted/PII: SSN, Credit Cards, Medical Records. Must be Encrypted at Rest.

2. Integrity Patterns

  • Checksums: Store md5/sha256 of files to detect bit-rot or tampering.
  • Foreign Keys: Enforce referential integrity in the DB. No orphans.
  • Versioning: Never overwrite critical data. Use v1, v2 or Event Sourcing AppendedOnly.

3. Lineage

  • Answer: "Where did this specific value in the dashboard come from?"
  • Track: Source System -> ETL Job -> Warehouse -> BI Tool.

4. Retention & Deletion (GDPR/CCPA)

  • TTL: Auto-delete logs after X days.
  • Right to be Forgotten: Implementation of a HardDeleteUser workflow that purges PII from all tables/backups (crypto-shredding).
