# Centralizing JDBC metadata

To centralize DB table based metadata into a JDBC connection under the Metadata node of the Repository tree view, the procedure is made of two separate but closely related tasks:

1. Set up a JDBC connection.

2. Retrieve the table schemas.

The sections below describe how to complete the tasks in detail.

For an example of using a JDBC connection, see [Data Integration Job Examples](https://help.qlik.com/talend/r/en-US/8.0/data-integration-job-examples).
