      Data Catalog Overview

      The Zetaris Data Catalog captures information on table and column metadata and tracks metadata changes. This metadata initially includes tables and columns, however, you can manually add or upload tags and descriptions. Data Catalog allows you to browse the existing defined data sources and the associated tables.

      You can access Zetaris Data Catalog through a command line and direct connection accessibility, allowing you to integrate workflow tools.
