Generating Data from Schema

Drafta can generate synthetic data by inferring structure from a schema. This feature enables users to create sample datasets for testing, prototyping, and validating their schema design.

How It Works​

Drafta analyzes a provided schema and generates realistic sample data based on field types and constraints. This includes:

  • String fields: Auto-generating names, addresses, emails, etc.
  • Number fields: Generating random but reasonable numerical values.
  • Boolean fields: Assigning true or false values.
  • Enum fields: Selecting values randomly from the defined set.
  • Object references: Resolving and linking referenced objects.

Basic Example​

User:
  id: string
  name: string
  age: number
  is_active: boolean
  gender: enum(male, female, other)
{
  "id": "a1b2c3d4",
  "name": "Alice Johnson",
  "age": 29,
  "is_active": true,
  "gender": "female"
}

Nested Data Example​

Product:
  id: string
  name: string
  price: number
  in_stock: boolean
  category: enum(electronics, clothing, books)
  manufacturer:
    name: string
    country: string
{
  "id": "p123456",
  "name": "Wireless Mouse",
  "price": 25.99,
  "in_stock": true,
  "category": "electronics",
  "manufacturer": {
    "name": "TechCorp",
    "country": "USA"
  }
}

Object References Example​

Order:
  order_id: string
  user: $User
  total_amount: number
  status: enum(pending, shipped, delivered, canceled)
  items: [$Product]
{
  "order_id": "o789012",
  "user": {
    "id": "a1b2c3d4",
    "name": "Alice Johnson",
    "age": 29,
    "is_active": true,
    "gender": "female"
  },
  "total_amount": 199.99,
  "status": "shipped",
  "items": [
    {
      "id": "p123456",
      "name": "Wireless Mouse",
      "price": 25.99,
      "in_stock": true,
      "category": "electronics",
      "manufacturer": {
        "name": "TechCorp",
        "country": "USA"
      }
    }
  ]
}

Recursive References Example​

Employee:
  id: string
  name: string
  position: string
  manager: $Employee
{
  "id": "e001",
  "name": "John Smith",
  "position": "CEO",
  "manager": null
}

{
  "id": "e002",
  "name": "Jane Doe",
  "position": "CTO",
  "manager": {
    "id": "e001",
    "name": "John Smith",
    "position": "CEO"
  }
}

This example demonstrates how Drafta handles recursive object references by ensuring appropriate linking and avoiding infinite loops.
