In Laravel, pivot tables serve as intermediary database tables that facilitate many-to-many relationships between two other tables. Acting as connectors, they store additional information about the relationship itself. Pivot tables contain foreign keys referencing the primary keys of the related tables, along with any extra columns necessary for relationship-specific data. By utilizing pivot tables, developers can seamlessly manage and query many-to-many relationships in Laravel, leveraging the powerful features provided by Laravel's Eloquent ORM. This simplifies the establishment and handling of complex relationships between models, enhancing the efficiency and flexibility of the application. To illustrate this, imagine we have two models: User and Role. A user can have multiple roles, while a role can be assigned to multiple users. By defining the relationships in the respective model classes, we can effortlessly interact with pivot tables. For instance, the User model would have a roles method defined using the belongsToMany function, specifying the Role model. Similarly, the Role model would have a users method defined in a similar manner. These columns establish the connections between users and roles. Now, let's explore how we can interact with pivot tables.

If you have ever had to tell a teammate to manually add a column to their local database schema after pulling in your changes from source control, you've faced the problem that database migrations solve. The Laravel Schema facade provides database agnostic support for creating and manipulating tables across all of Laravel's supported database systems. Typically, migrations will use this facade to create and modify database tables and columns. You may use the make:migration Artisan command to generate a database migration. Each migration filename contains a timestamp that allows Laravel to determine the order of the migrations:. Laravel will use the name of the migration to attempt to guess the name of the table and whether or not the migration will be creating a new table. If Laravel is able to determine the table name from the migration name, Laravel will pre-fill the generated migration file with the specified table. Otherwise, you may simply specify the table in the migration file manually. If you would like to specify a custom path for the generated migration, you may use the --path option when executing the make:migration command.
