The SQL Historian module expands the functionality of the [Historian Core](versioned_docs/version-8.3/getting-started/modules-overview/core-modules/tag-historian-module.md) module by providing the SQL Historian as an additional option. The SQL Historian leverages a SQL database for the storage and retrieval of historical data. 

:::note
The SQL Historian module requires the Historian Core module to be installed on the same Gateway.

## Connecting to the SQL Historian

When you have both the Historian Core module and SQL Historian module installed, you simply need to navigate to **Services** > **Historians** > **Historians** and select **Create Historian** to add a SQL Historian to your Gateway. From here you can choose where to store your tag history, and configure data partitioning and data pruning settings.  

This historian type is well-suited for systems that require robust reporting, integration with external tools, or long-term historical data storage.
