# Database support for CDC

The CDC feature is available for the following databases: AS/400, DB2, Informix, Ingres, MS SQL Server, MySQL, Oracle, PostgreSQL, Sybase, and Teradata. Note that the CDC feature works only with database systems running on the same server.

The following table provides information about the database support for CDC. As explained in the [CDC architectural overview](https://help.qlik.com/talend/en-US/studio-user-guide/8.0-R2025-01/change-data-capture), the CDC feature captures the updated data from a Source database and sends the captured data to a Change table, where the Talend Studio Job reads the data from.
