UNDER THE HOOD

Inside the Engine: Schema to Database

  1. Stage 1

    Understand your data

    • Multi-dialect SQL parsing
    • Reasoning-model schema design
    • Your rows never uploaded
  2. Stage 2

    Map every relationship

    • Cross-table dependency graph
    • Parents-first topological ordering
    • Cycle detection and resolution
    • Realistic link distributions
  3. Stage 3

    Plan with domain knowledge

    • 232 data types, 222 built-in generators
    • 200+ automatic field links
    • 22 generation methods
    • Check-digit-valid identifiers
  4. Stage 4

    Guardrails before generation

    • Schema validation on every rule
    • Self-correction repair rounds
    • Sandboxed formula engine
  5. Stage 5

    Generate deterministically

    • Seeded, reproducible runs
    • Measured statistical correlations
    • Cross-table lookups and roll-ups
    • Per-entity time-series continuity
  6. Stage 6

    Write language in context

    • Context-aware AI batches
    • Multi-model fallback
    • Engine-owned keys
  7. Stage 7

    Enforce and repair

    • Constraint checks on every value
    • Automatic repair loop
    • Load-safe anomaly injection
    • Full quality report
  8. Stage 8

    Export and verify

    • Dialect-aware SQL writer
    • Integrity-checked database file

The exact methods and tuning stay ours. The guarantees are yours.
