Use CData Connect AI to connect to live Cloudant data and build visualizations in Tableau.

Tableau is a visual analytics platform transforming the way businesses use data to solve problems. When paired with CData Connect AI, you get instant, cloud-to-cloud access to Cloudant data for visualizations, dashboards, and more. This article shows how to connect to Cloudant and build visualizations from Cloudant data in Tableau.

CData Connect AI provides a pure SQL Server, cloud-to-cloud interface for Cloudant, allowing you to easily build visualizations from live Cloudant data in Tableau without installing connectors. As you build visualizations, Tableau generates SQL queries to gather data. Using optimized data processing out of the box, CData Connect AI pushes all supported SQL operations (filters, JOINs, etc) directly to Cloudant, leveraging server-side processing to quickly return Cloudant data.

Add a Personal Access Token

When connecting to Connect AI through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect AI. It is best practice to create a separate PAT for each service to maintain granularity of access.

  1. Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
  2. On the Settings page, go to the Access Tokens section and click Create PAT.
  3. Give the PAT a name and click Create. 👁 Creating a new PAT
  4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured and a PAT generated, you are ready to connect to Cloudant data from Tableau.
