How Relational Foreign Key Dependencies Are Managed Exactly
Traditional mock tools populate tables in isolation, causing foreign key constraint violations and broken database seeds. Sylvaera solves this with automated topological ordering and referential key sampling.
Tables are sorted into dependency tiers (Root Level 0 âž” Child Level 1 âž” Grandchild Level 2). Parent tables with zero foreign keys are always populated first.
When populating child tables (like `orders` or `payments`), the foreign key column strictly samples from the actual primary keys generated in the parent table (`users.id`). No orphan records ever occur.
Column names like `doctor_name`, `consultation_fee`, `specialty`, and `city` produce realistic, culturally authentic records aligned with your target country context.
