Build Teradata Visualizations in Tableau Online

Use the CData Cloud Hub to create a virtual MySQL Database for Teradata data and build visualizations in Tableau Online.

Tableau Online is an analytics platform fully hosted in the cloud. When paired with the CData Cloud Hub, you get instant, cloud-to-cloud access to Teradata data for visualizations, dashboards, and more. This article shows how to create a virtual database for Teradata and build visualizations from Teradata data in Tableau Online.

The CData Cloud Hub provides a pure MySQL, cloud-to-cloud interface for Teradata, allowing you to easily build visualizations from live Teradata data in Tableau Online without installing connectors or publishing worksheets and data sources from Tableau Desktop. As you build visualizations, Tableau Online generates SQL queries to gather data. Using optimized data processing out of the box, the CData Cloud Hub pushes all supported SQL operations (filters, JOINs, etc) directly to Teradata, leveraging server-side processing to quickly return Teradata data.

Create a Virtual MySQL Database for Teradata Data

CData Cloud Hub uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Login to Cloud Hub and click Databases.
  2. Select "Teradata" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Teradata.

    To connect to Teradata, provide authentication information and specify the database server name.

    • User: Set this to the username of a Teradata user.
    • Password: Set this to the password of the Teradata user.
    • DataSource: Specify the Teradata server name, DBC Name, or TDPID.
    • Port: Specify the port the server is running on.
    • Database: Specify the database name. If not specified, the default database is used.
  4. Click Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to build visualizations in Tableau Online.

Visualize Live Teradata Data in Tableau Online

The steps below outline creating a new data source in Tableau Online based on the virtual Teradata database in Cloud Hub and building a simple visualization from the data.

  1. Log into Tableau Online, select a project, and create a new workbook.
  2. In the new workbook, choose the MySQL Connector from the data wizard and fill in the values for your Cloud Hub instance.
  3. Select your newly created database and the table(s) you wish to visualize (defining relationships for JOINed tables as needed).
  4. Select Dimensions and Measures and configure your visualization.

SQL Access to Teradata Data from Cloud Applications

At this point, you have a direct, cloud-to-cloud connection to live Teradata data from your Tableau Online workbook. You can create new visualizations, build dashboards, and more, with no need to publish data sources and workbooks from Tableau Desktop.
