# Project connections

Project connections are data connections linked to a specific project in Recurve. For each project connection, you can define the connection type and specify separate target databases for **development** and **production** environments. This setup provides smooth transitions when promoting changes from development to production.

While a project can have multiple project connections, only one connection can be set as the primary database at a time. This primary database, also called the **analytics database**, is optimized for reading and aggregating data in large volumes. All models in your project will be executed and built under the analytics database.

This guide shows you how to create a project connection and set the analytics database.

## Create a project connection

Follow these steps:

1. Open your project and go to **Settings** > **Data connections**.
2. In the **Define connection** section, click **+ Add connection**.
3. Provide the connection name and the connection type for development and production environments.

   Note that the connection type must be the same for both development and production environments.
