Visualize Azure Table Data in Tableau

The CData ODBC driver for Azure Table enables you integrate Azure Table data into Tableau dashboards.

The CData ODBC Driver for Azure Table enables you to access live Azure Table data in business intelligence tools like Tableau. In this article, you will integrate Azure Table data into a dashboard that reflects changes to Azure Table data in real time.

The CData ODBC drivers offer unmatched performance for interacting with live Azure Table data in Tableau due to optimized data processing built into the driver. When you issue complex SQL queries from Tableau to Azure Table, the driver pushes supported SQL operations, like filters and aggregations, directly to Azure Table and utilizes the embedded SQL engine to process unsupported operations (often SQL functions and JOIN operations) client-side. With built-in dynamic metadata querying, you can visualize and analyze Azure Table data using native Tableau data types.

Connect to Azure Table as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Specify your AccessKey and your Account to connect. Set the Account property to the Storage Account Name and set AccessKey to one of the Access Keys. Either the Primary or Secondary Access Keys can be used. To obtain these values, navigate to the Storage Accounts blade in the Azure portal. You can obtain the access key by selecting your account and clicking Access Keys in the Settings section.

When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Add Azure Table Data to a Dashboard

  1. Click Connect to Data -> More Servers -> Other Databases (ODBC).
    Select the CData Data Source Name (for example: CData AzureTables Source).
  2. In the Database menu, select CData.
  3. In the Table box, enter a table name or click New Custom SQL to enter an SQL query. This article retrieves the NorthwindProducts table.
  4. Drag the table onto the join area. At this point, you can include multiple tables, leveraging the built-in SQL engine to process complex data requests.
  5. In the Connection menu, select the Live option, so that you skip loading a copy of the data into Tableau and instead work on real-time data. The optimized data processing native to CData ODBC drivers enables unmatched performance in live connectivity.
  6. Click the tab for your worksheet. Columns are listed as Dimensions and Measures, depending on the data type. The CData driver discovers data types automatically, allowing you to leverage the powerful data processing and visualization features of Tableau.
  7. Drop the Name column in the Dimensions pane onto the dashboard. When you select dimensions, Tableau builds a query to the driver. The results are grouped based on that dimension. In Tableau, the raw query is automatically modified as you select dimensions and measures.
  8. Drag the Price column in the Measures field onto the Detail and Color buttons. Tableau executes the following query:

    SELECT Name, SUM(Price) FROM NorthwindProducts GROUP BY Name

    When you select a measure, Tableau executes a command to the driver to calculate a summary function, such as SUM, AVG, etc., on the grouped values. The SQL engine (embedded within the driver) is leveraged to process the aggregation of the data, where needed, providing a seamless experience in Tableau, regardless of the data source.

    To change the summary function, open the Price menu and select the summary you want in the Measure command.

  9. You can create other charts using dimensions and measures to build SQL queries visually:

With the CData ODBC Driver for Azure Table, you get live connectivity to your Azure Table data, allowing you to build real-time charts, graphs, and more.
