Definition

Migrations (are the short name for Database Migrations).

Migrations are the version control of your database. They are very useful for generating and documenting the database tables.

Principles

• Migrations SHOULD be created inside the Containers folders.

• Migrations will be autoloaded by the framework.

Rules

• No need to publish the DB Migrations. Just run the artisan migrate command and Laravel will read the Migrations from the Containers.

Folder Structure

   - app
      - Containers
          - {section-name}
              - {container-name}
                  - Data
                      - Migrations
                          - 2200_01_01_000001_create_something_table.php
                          - ...

Code Samples

User CreateDemoTable Migrations

class CreateDemoTable extends Migration
{
    public function up()
    {
        Schema::create('demos', function (Blueprint $table) {
            $table->increments('id');
            // ...
            $table->timestamps();
            $table->softDeletes();
        });
    }
