# Teradata metadata collector

The Teradata metadata collector harvests read-only metadata from a Teradata account.

The collector harvests metadata from Teradata, including user defined functions, stored procedures, triggers, user defined types, and user defined methods.

## Authentication supported

The collector authenticates to Teradata using [username and password](https://docs.teradata.com/r/ODBC-Driver-for-Teradata-User-Guide/June-2022/Network-Security/Authentication-Mechanisms). Before running the collector, set up a dedicated database user with the required permissions. See [Prepare to run the Teradata Collector](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/integrate-applications/prepare-to-run-teradata-collector.md).

</table>Profiling and sampling specific information.

If you include the profiling and sampling specific parameters while running the collector, the following additional information is harvested for columns.

**Note:** Users or roles must have read access to data to harvest profiling information \(column statistics\).

</table>## Relationships between objects

By default, the harvested metadata includes catalog pages for the following resource types. Each catalog page has a relationship to the other related resource types. If the metadata presentation for this data source has been customized, you might see other resource pages and relationships.

</table>## Lineage for Teradata

The Teradata collector collects the following lineage information.

**Note:** Lineage for SQL statements defined via variable statements is not supported.

</th></tr></thead><tbody><tr><td>

View

</td><td>

The collector identifies the associated column in an upstream view or table: -   Where the data is sourced from
-   That sort the rows via ORDER BY
-   That filter the rows via WHERE/HAVING
-   That aggregate the rows via GROUP BY

</td></tr><tr><td>

Stored procedure

</td><td>

The collector identifies: -   The associated column in an upstream view or table
-   Where the data is sourced from
-   That sort the rows via ORDER BY
-   That filter the rows via WHERE/HAVING
-   That aggregate the rows via GROUP BY
-   The downstream table that has its data updated

 Lineage is not available in the following cases:

 -   The SQL statement in stored procedures contains the SELECT INTO clause
-   Stored procedures with multiple insert statements
-   Stored procedures used to create tables or transient tables created during the execution scope of a stored procedure
