因為 SQLModel 建立在 SQLAlchemy 之上，你可以輕鬆使用 SQLAlchemy 所支援的任何資料庫（因此 SQLModel 也支援），例如：

* PostgreSQL
* MySQL
* SQLite
* Oracle
* Microsoft SQL Server，等等。

在這個範例中，我們會使用 SQLite，因為它只用到單一檔案，而且 Python 內建支援。你可以直接複製這個範例並原樣執行。

之後，在你的正式環境應用中，你可能會想使用像 PostgreSQL 這類的資料庫伺服器。

由于 SQLModel 基于 SQLAlchemy，因此你可以轻松使用任何由 SQLAlchemy **支持的数据库**（这也让它们被 SQLModel 支持），例如：

* PostgreSQL
* MySQL
* SQLite
* Oracle
* Microsoft SQL Server 等

在这个示例中，我们将使用 **SQLite**，因为它使用单个文件，并且 Python 对其有集成支持。因此，你可以直接复制这个示例并运行。

之后，对于你的生产应用程序，你可能会想要使用像 **PostgreSQL** 这样的数据库服务器。

/// tip | 提示

Care should be taken when using vector instructions to ensure that they are available at
runtime.
To use vector instructions a machine must have both the vector facility (bit 129 in the
facility list) and kernel support.
Without kernel support a vector instruction will have no effect (it will be equivalent
to a <code>NOP</code> instruction).
