### Cross-cutting architecture modules

There are some additional cross-cutting architecture modules that aren't themselves platforms:

#### Enterprise integration

Provides cross-cutting integration with Gradle's commercial product.

#### IDE integration

Provides cross-cutting integration with IDEs and other tooling.

#### Build infrastructure

 Cela aide beaucoup pendant le **développement**, mais vous **ne devriez pas** l'utiliser en **production**.

* Microsoft SQL Server, etc.

In this example, we'll use **SQLite**, because it uses a single file and Python has integrated support. So, you can copy this example and run it as is.

Later, for your production application, you might want to use a database server like **PostgreSQL**.
