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();        });    }
    public function down()    {        Schema::drop('demos');    }}
