# Supported Databases

Atoti Market Risk offers two levels of support for databases to work with DirectQuery.

## Native support

These databases are natively supported by Atoti Market Risk. The Solution provides a fully tested standard implementation, with reference data and documentation for connecting to these databases.

With a natively supported database, Atoti Market Risk provides:

* Documentation on required configuration properties to connect to the remote database.
* Reference SQL queries to create the database tables (these are available in `mr-directquery/src/test/resources/databases`).
* Reference data in a format compatible with the specific database (for Databricks this is available in `mr-directquery/src/test/resources/databases/databricks/data`. For Microsoft SQL Server and Snowflake you can use the primary dataset in `mr-application/src/main/resources/data`).
* Databases tested for computational accuracy.

### Natively supported databases

Atoti Market Risk provides a fully tested standard implementation, with reference data and documentation for the following databases:

* [Databricks](https://www.databricks.com)
* [Microsoft SQL](https://www.microsoft.com/en-us/sql-server/)
* [Snowflake](https://www.snowflake.com/)

For detailed steps on how to connect to one of these databases, see [Getting started](.).

### Non-native support

Atoti Server supports connecting to other compatible databases, but Atoti Market Risk currently does not. You can manage these databases yourself, but we do not document the implementation steps required.

If your chosen Database isn’t natively supported, you can contact us for implementation support or refer to the Atoti Server [DirectQuery documentation](https://docs.activeviam.com/products/atoti/server/6.1.11/docs/directquery/getting_started/) to customize with a different database.

<Note>
  Your chosen database **must** be one [supported by Atoti Server DirectQuery](https://docs.activeviam.com/products/atoti/server/6.1.11/docs/directquery/compatibility/)
