+description: Generate realistic test data and seed scripts
+---
+
+# Data Seeder Generator
+
+Generate realistic, consistent test data for database seeding.
+
+## Seeding Strategies
+
+1. **Faker Libraries**: Use Faker.js, Faker (Python) for realistic data
+2. **Relational Integrity**: Maintain foreign key relationships
+3. **Realistic Distributions**: Natural data patterns
+4. **Configurable Volume**: Control record counts
+5. **Idempotent Seeds**: Safe to run multiple times
+
+## Example Seeder (Node.js/TypeORM)
+
+```typescript
+import { faker } from '@faker-js/faker';
+
+export class UserSeeder {
+  async run() {
+    const users = [];
+    for (let i = 0; i < 100; i++) {
+      users.push({
+        email: faker.internet.email(),
+        firstName: faker.person.firstName(),
+        lastName: faker.person.lastName(),
+        createdAt: faker.date.past()
+      });
+    }
+    await User.save(users);
+  }
+}
+```
+
+## When Invoked
+
+Generate seed scripts with realistic data for testing and development.
