# Manage data sources

With Pentaho Data Catalog, you can process data from file systems and relational databases.

To process data from these systems, Data Catalog establishes a data source definition. This data source stores the connection information to your sources of data, including their access URLs and user credentials. The number of data sources you can add is determined by your license agreement.

**Note:** Refer to the product release notes for the latest supported versions.

The following data sources are supported:

***

<sup>1</sup> AWS S3, HCP, Minio, and VSP One data sources support **Skip SSL validation** when the data source uses a self-signed SSL certificate. Use this option only in non-production environments. To enable SSL validation, install user-provided SSL certificates into Data Catalog instead. For more information, see [Advanced configuration](/pdc-admin/ldc-advanced-configuration-ut_cp.md#install-user-provided-ssl-certificates).
