Create Datasets from Azure Data Catalog in Domo Workbench and Build Visualizations of Azure Data Catalog Data in Domo

Domo helps you manage, analyze, and share data across your entire organization, enabling decision makers to identify and act on strategic opportunities. Domo Workbench provides a secure, client-side solution for uploading your on-premise data to Domo. The CData ODBC Driver for Azure Data Catalog links Domo Workbench to operational Azure Data Catalog data. You can build datasets from Azure Data Catalog data using standard SQL queries in Workbench and then create real-time visualizations of Azure Data Catalog data in the Domo service.

The CData ODBC Drivers offer unmatched performance for interacting with live Azure Data Catalog data in Domo due to optimized data processing built into the driver. When you issue complex SQL queries from Domo to Azure Data Catalog, the driver pushes supported SQL operations, like filters and aggregations, directly to Azure Data Catalog 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 Data Catalog data using native Domo data types.

Connect to Azure Data Catalog 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.

You can optionally set the following to read the different catalog data returned from Azure Data Catalog.

CatalogName: Set this to the CatalogName associated with your Azure Data Catalog. To get your Catalog name, navigate to your Azure Portal home page > Data Catalog > Catalog Name

Connect Using OAuth Authentication

You must use OAuth to authenticate with Azure Data Catalog. OAuth requires the authenticating user to interact with Azure Data Catalog using the browser. For more information, refer to the OAuth section in the help documentation.

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.

After creating a DSN, you will need to create a dataset for Azure Data Catalog in Domo Workbench using the Azure Data Catalog DSN and build a visualization in the Domo service based on the dataset.

Build a Dataset for Azure Data Catalog Data

You can follow the steps below to build a dataset based on a table in Azure Data Catalog in Domo Workbench using the CData ODBC Driver for Azure Data Catalog.

1. Open Domo Workbench and, if you have not already, add your Domo service server to Workbench. In the Accounts submenu, click Add New, type in the server address (i.e., domain.domo.com) and click through the wizard to authenticate.
2. In the DataSet Jobs submenu, click Add New.
3. Name the dataset job (i.e., ODBC Azure Data Catalog Tables), select ODBC Connection Provider as the transport method, and click through the wizard.
4. In the newly created DataSet Job, navigate to Source and click to configure the settings.
5. Select System DSN for the Connection Type.
6. Select the previously configured DSN (CData AzureDataCatalog Sys) for the System DSN.
7. Click to validate the configuration.
8. Below the settings, set the Query to a SQL query: SELECT * FROM Tables NOTE: By connecting to Azure Data Catalog data using an ODBC driver, you simply need to know SQL in order to get your data, circumventing the need to know Azure Data Catalog-specific APIs or protocols.
9. Click preview.
10. Check over the generated schema, add any transformations, then save and run the dataset job.

With the dataset job run, the dataset will be accessible from the Domo service, allowing you to build visualizations, reports, and more based on Azure Data Catalog data.

Create Data Visualizations

With the DataSet Job saved and run in Domo Workbench, we are ready to build visualizations of the Azure Data Catalog data in the Domo service.

1. Navigate to the Data Center.
2. In the data warehouse, select the ODBC data source and drill down to our new dataset.
3. With the dataset selected, choose to create a visualization.
4. In the new card:
   • Drag a Dimension to the X Value.
   • Drag a Measure to the Y Value.
   • Choose a Visualization.

With the CData ODBC Driver for Azure Data Catalog, you can build custom datasets based on Azure Data Catalog data using only SQL in Domo Workbench and then build and share visualizations and reports through the Domo service.
