而且您还可以将 Alembic 用于“迁移”（这是它的主要工作）。

“迁移”是每当您更改 SQLAlchemy 模型的结构、添加新属性等以在数据库中复制这些更改、添加新列、新表等时所需的一组步骤。

您可以在[Full Stack FastAPI Template](https://fastapi.tiangolo.com/zh/project-generation/)的模板中找到一个 FastAPI 项目中的 Alembic 示例。具体在[`alembic`代码目录中](https://github.com/tiangolo/full-stack-fastapi-template/tree/master/backend/app/alembic)。

### 创建依赖项

现在使用我们在`sql_app/database.py`文件中创建的`SessionLocal`来创建依赖项。

このマネージャー・ プロセスは、おそらくIPの**ポート**でリッスンしているものです。そして、すべての通信をワーカー・プロセスに転送します。

これらのワーカー・プロセスは、アプリケーションを実行するものであり、**リクエスト**を受けて**レスポンス**を返すための主要な計算を行い、あなたが変数に入れたものは何でもRAMにロードします。

<img src="/img/deployment/concepts/process-ram.svg">

そしてもちろん、同じマシンでは、あなたのアプリケーションとは別に、**他のプロセス**も実行されているでしょう。

興味深いことに、各プロセスが使用する**CPU**の割合は時間とともに大きく**変動**する可能性がありますが、**メモリ（RAM）**は通常、多かれ少なかれ**安定**します。
