Introduction to Migrations
Laravel migrations provide a version control system for database structure. Developers can define tables and columns using PHP migration files.
Creating a Migration
Laravel Artisan provides commands for creating migration files. Developers can then define columns, indexes and relationships inside the migration.
Running Migrations
The migrate command runs pending migrations and creates or modifies database tables according to the migration definitions.
Foreign Keys
Foreign keys help maintain relationships between related database tables. Laravel provides convenient methods for defining foreign key constraints.
Rollback
Migrations can be rolled back when developers need to reverse database changes during development.
Conclusion
Laravel migrations make database structure easier to manage across development and production environments.
