Laravel 5 Migrations

标签：

Laravel migrations provide mechanisms for creating and modifying database tables. Migrations are database agnostic. This means you do not have to worry about the specific SQL syntax for the database engine that you are creating tables for. Migrations also allow you to roll back the most recent changes that you made to a database.

Create migration table
Run the following artisan command to create a migration table in Larashop database.
php artisan migrate:install
You will get the following message
Migration table created successfully.

$table->timestamps(); is used to automatically create two time stamp fields namely created_at and updated_at.

Database seeding
In this section, we are going to add dummy data to our database. Seeding is a term that is used to describe the process of adding test data to the database.
