FAQ Frequently Asked Questions

What types of validation rules can I create?
The builder supports row count validation, checksum comparisons, NULL checks, duplicate detection, referential integrity validation, data type verification, range checks, pattern matching, and custom business rule validation across multiple database systems.
How do I validate a database migration?
Define your source and target tables, select validation types (counts, checksums, integrity), and the tool generates SQL queries for both databases. Run these queries before and after migration to ensure data accuracy and completeness.
Which database systems are supported?
The tool generates validation queries for MySQL, PostgreSQL, SQL Server, and Oracle. Each query is optimized for the specific database syntax and functions. All processing happens locally in your browser for security.
How accurate are the checksum validations?
The tool uses industry-standard MD5 and SHA algorithms for checksums, providing extremely high accuracy for data comparison. For large datasets, we recommend sampling strategies to balance performance with validation coverage.
Can I save validation rule templates?
Yes, you can export your validation rules as JSON templates for reuse. Import these templates for similar migrations or create a library of standard validation patterns for your organization.
