CoreMedia CMS uses repositories for data storage, therefore it requires one or more external relational databases. A correctly installed and activated database is prerequisite for the operation of CoreMedia CMS. How to connect the CoreMedia system to databases is described in detail for the different databases in the Content Server Manual.
![[Note]](../common/images/note.png) | Note |
|---|---|
It is strongly recommended to use a UTF-8 enabled database for your CoreMedia CMS repository. |
The databases have only been tested in CoreMedia compliant operating environments and therefore are only approved on these platforms. For all supported environments see the [Supported Environments] document at https://documentation.coremedia.com/dxp8/supported-environments-en.pdf.
