Awarded for completing Data Modelling, Constraints and Integrity for Secure Systems and passing its exam, demonstrating the ability to design keys, constraints, nullability and tenancy models that enforce correctness and isolation at the database layer rather than relying on application code alone.
Certificates are designed to be checked, not just displayed.
The credential is valid for 12 months from issue. Its public page states the expiry date, and renewing means passing the current exam again — so the credential always reflects the current material.
