Overview

The OCF connector for SQL Server was developed by Alation and is available as a Zip file that can be uploaded and installed in the Alation application. The connector is compiled together with the required database driver, so no additional effort is needed to procure and install the driver.

To download the SQL Server OCF connector package, go to the Alation Connector Hub available from the Customer Portal. Go to Customer Portal > Connectors > Alation Connector Hub. Only Alation users with access to the Customer Portal can access the Alation Connector Hub. If you don’t have access to the Customer Portal, contact Alation Support.

This connector should be used to catalog SQL Server and/or Azure SQL Managed Instance as a data source in Alation. The connector catalogs SQL Server objects such as tables, columns, views, primary keys, foreign keys, functions, and function definitions. It enables end-users to search and find SQL Server objects from the Alation user interface.

Use the instructions given in this guide to install and manage the connector.
