Data Migration Validator Skill
Validates data integrity throughout the migration process with comprehensive verification checks and reconciliation reporting.
Purpose
Enable data validation for:
- Row count validation
- Checksum verification
- Sample data comparison
- Referential integrity checking
- Business rule validation
Capabilities
1. Row Count Validation
- Compare source/target counts
- Track by table/partition
- Identify discrepancies
- Generate count reports
2. Checksum Verification
- Calculate table checksums
- Compare hash values
- Identify data drift
- Verify data consistency
3. Sample Data Comparison
- Random sample selection
- Field-by-field comparison
- Statistical sampling
- Confidence scoring
4. Referential Integrity Checking
- Verify foreign keys
- Check orphaned records
- Validate relationships
- Report violations
5. Business Rule Validation
- Apply custom rules
- Check data constraints
- Verify transformations
- Validate calculations
6. Reconciliation Reporting
- Generate audit reports
- Track discrepancies
- Document exceptions
- Provide sign-off reports
