How it works
Add ownership and audit fields
The selected tenancy and history needs add practical MVP columns.
Score complexity
Entity count, relationships and full audit requirements increase schema complexity.
Frequently asked questions
Is the output production-ready SQL?
No. It is a relational design starter that needs review for types, constraints, privacy and migrations.
Why require one workflow?
A bounded workflow prevents speculative tables for features outside MVP scope.
Does it support many-to-many relationships?
The starter flags likely join-table needs but a developer must finalize cardinality.
What about sensitive data?
Minimize collection and review access, retention, encryption and legal requirements separately.
