Build Quandl Visualizations in Tableau Online

Use the CData Cloud Hub to create a virtual MySQL Database for Quandl 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 Quandl data for visualizations, dashboards, and more. This article shows how to use a MySQL client to create a virtual database for Quandl and build visualizations from Quandl data in Tableau Online.

The CData Cloud Hub provides a pure MySQL, cloud-to-cloud interface for Quandl, allowing you to easily build visualizations from live Quandl 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 Quandl, leveraging server-side processing to quickly return Quandl data.

Create a Virtual MySQL Database for Quandl 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 "Quandl" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Quandl.

    Quandl uses an API key for authentication. See the help documentation for a guide to obtaining the APIKey property.

    Additionally, set the DatabaseCode connection property to the code identifying the Database whose Datasets you want to query with SQL. You can search the available Databases by querying the Databases view.

  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 Quandl Data in Tableau Online

The steps below outline creating a new data source in Tableau Online based on the virtual Quandl 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 Quandl Data from Cloud Applications

At this point, you have a direct, cloud-to-cloud connection to live Quandl 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.
