# Managing MDM databases

The list of available databases depends on which version of Talend MDM you are using.

For more information on compatible databases, see [Compatible databases](https://help.qlik.com/talend/en-US/installation-guide-windows/7.2/compatible-databases "The following tables provide information on the recommended and supported databases you can use with Talend server modules.").

Note that, if you are working with an Oracle database, you must make sure that the Oracle user which Talend MDM uses to connect to the database has not been assigned the DBA role, or else you may encounter unexpected issues.
