Schema Definition

Summary

Declaring your data models — fields, types, relationships, constraints — in your ORM's format, which then generates or validates against your actual database schema.

• 1Define a schema with at least one one-to-many and one many-to-many relationship.
• 2Learn how your ORM's schema syntax maps to underlying SQL `CREATE TABLE` statements.
• 3Practice adding a new field to an existing schema and generating the migration.
