Teradata Component

Overview

Semarchy xDI allows to work with Teradata to produce fully customized Data Flows.

The database structure can be entirely reversed in Metadata and then used in Mappings and Processes to design and adapt the business rules to meet the user’s requirements.

Install the Teradata Component

If you did not install it yet, install the Teradata component in Designer by following the component installation process.

Third-party libraries

Due to licensing restrictions, we cannot distribute the Java libraries for this database. You must obtain them yourself.

After you have the necessary Teradata libraries, create a Teradata module for your project, and add the libraries to the module.
