Create Datasets from HPCC Systems in Domo Workbench and Build Visualizations of HPCC Systems Data in Domo

Use the CData ODBC Driver for HPCC Systems to create datasets from HPCC Systems data in Domo Workbench and then build visualizations in the Domo service.

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 HPCC Systems links Domo Workbench to operational HPCC Systems data. You can build datasets from HPCC Systems data using standard SQL queries in Workbench and then create real-time visualizations of HPCC Systems data in the Domo service.

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

Connect to HPCC Systems 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.

To connect, set the following connection properties: Set URL to the machine name or IP address of the server and the port the server is running on, for example, https://server:port. The User and Password are required to authenticate to the HPCC Systems cluster specified in the URL. Note that LDAP authentication is not currently supported by our ODBC driver.

Set Version to the WsSQL Web server version. Note that if you have not already done so, you will need to install the WsSQL service on the HPCC Systems server. The WsSQL Web service is used to interact with the underlying HPCC Systems platform.

Set Cluster to the target cluster.

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 HPCC Systems in Domo Workbench using the HPCC Systems DSN and build a visualization in the Domo service based on the dataset.

Build a Dataset for HPCC Systems Data

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

  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 HPCC Systems hpcc::test::orders), 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 HPCC Sys) for the System DSN.
  7. Click to validate the configuration.
  8. Below the settings, set the Query to a SQL query: SELECT * FROM hpcc::test::orders NOTE: By connecting to HPCC Systems data using an ODBC driver, you simply need to know SQL in order to get your data, circumventing the need to know HPCC Systems-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 HPCC Systems data.

Create Data Visualizations

With the DataSet Job saved and run in Domo Workbench, we are ready to build visualizations of the HPCC Systems 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 HPCC Systems, you can build custom datasets based on HPCC Systems data using only SQL in Domo Workbench and then build and share visualizations and reports through the Domo service.
