# Database

> Configure repository preferences and environment settings for a managed database service.

This guide explains how to configure a **Database** resource in Revolte. Databases are modular building blocks that can be deployed standalone or as part of a combined full-stack preset.

## Combined deployments

If your application requires compute (API) alongside a database, you should select one of the following presets during the **Choose a Preset** step:

* **Webservice + Database**
* **Webservice + Database + StorageBucket**
* **Webservice + Database + Cache**
* **Webservice + Database + StorageBucket + Cache**

> **Note:** For all combined presets, the core configuration workflow is identical to a standard [Web Service](/guides/deployments/web-services). This guide focuses specifically on the supplemental **Database** settings described below.

<Steps>
  <Step title="Choose a Preset">
    Select the **Database** tile for a standalone instance, or choose one of the combined presets listed above for full-stack deployments.
  </Step>

  <Step title="Database — Environment Settings">

    The **QA** environment tab is selected. You can define independent resource specifications for **Preview**, **QA**, **Staging**, and **Production**.

    The center panel shows the Database form for the active environment:

    * **Service Name** — Enter a unique identifier for this database instance (e.g., `production_db`).
    * **Specifications**
      * **Engine Type** — Choose between supported database engines (e.g., `PostgreSQL`, `MySQL`).
      * **CPU & Memory** — Choose a compute tier for your database workload. Available options:
        * `2 CPU and 1 GB Memory`
        * `2 CPU and 2 GB Memory`
        * `2 CPU and 4 GB Memory`
        * `2 CPU and 8 GB Memory`
        * `4 CPU and 16 GB Memory`
        * `8 CPU and 32 GB Memory`
        * `16 CPU and 64 GB Memory`
        * `48 CPU and 192 GB Memory`
        * `96 CPU and 384 GB Memory`
      * **Storage value** — Disk space in GB allocated to the database (e.g., `50`).
  </Step>
</Steps>

> **Tip:** Revolte automatically generates connection strings for your database and injects them as secrets into linked services.
