Use CData Connect Cloud to create a virtual SQL Server Database for Google Data Catalog data and build visualizations in Tableau Online.

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

CData Connect Cloud provides a pure SQL Server, cloud-to-cloud interface for Google Data Catalog, allowing you to easily build visualizations from live Google Data Catalog 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, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc) directly to Google Data Catalog, leveraging server-side processing to quickly return Google Data Catalog data.

Create a Virtual SQL Server Database for Google Data Catalog Data

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

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

    Google Data Catalog uses the OAuth authentication standard. Authorize access to Google APIs on behalf on individual users or on behalf of users in a domain.

    Before connecting, specify the following to identify the organization and project you would like to connect to:

    • OrganizationId: The ID associated with the Google Cloud Platform organization resource you would like to connect to. Find this by navigating to the cloud console.

      Click the project selection drop-down, and select your organization from the list. Then, click More -> Settings. The organization ID is displayed on this page.

    • ProjectId: The ID associated with the Google Cloud Platform project resource you would like to connect to.

      Find this by navigating to the cloud console dashboard and selecting your project from the Select from drop-down. The project ID will be present in the Project info card.

    When you connect, the OAuth endpoint opens in your default browser. Log in and grant permissions to the application to completes the OAuth process. For more information, refer to the OAuth section in the Help documentation.

  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 Google Data Catalog Data in Tableau Online

The steps below outline creating a new data source in Tableau Online based on the virtual Google Data Catalog database in Connect Cloud 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 Microsoft SQL Server Connector from the data wizard and fill in the values for your Connect Cloud instance.
    NOTE: Be sure to check the "Require SSL" checkbox.
  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 Google Data Catalog Data from Cloud Applications

At this point, you have a direct, cloud-to-cloud connection to live Google Data Catalog 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.
