# Managing SQL databases

You can store the MDM repository and your master data records in a SQL database. For licensing reasons, if you want to use any of the supported SQL databases other than the H2 database embedded with the product, you need to download and manually install the database drivers in <TomcatPath>/webapps/talendmdm/WEB-INF/lib before using Talend products.

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