Data Vault should allow for high-concurrency loading.
Check that Satellites are correctly attached to their parent Hub/Link and that the Hash_Diff (used for change detection) is calculating correctly. 2. Load Pattern Testing (Technical ETL) Testing Data Vault-Based Data Warehouse
Data Vault excels at "insert-only" logic. Your tests should mirror this. Data Vault should allow for high-concurrency loading
Verify that the hashing algorithm (MD5 or SHA-1) produces identical keys for the same business keys across different source systems. 4. Point-in-Time (PIT) & Bridge Table Validation Testing Data Vault-Based Data Warehouse
Ensure "Zero Keys" or "Ghost Records" exist in Hubs to handle late-arriving data or missing lookups without breaking the model. 3. Data Integrity & Reconciliation This ensures that "what went in is what came out."
