Create Datasets from Oracle in Domo Workbench and Build Visualizations of Oracle 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 Oracle links Domo Workbench to operational Oracle data. You can build datasets from Oracle data using standard SQL queries in Workbench and then create real-time visualizations of Oracle data in the Domo service.

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

Connect to Oracle 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 to Oracle, you'll first need to update your PATH variable and ensure it contains a folder location that includes the native DLLs. The native DLLs can be found in the lib folder inside the installation directory. Once you've done this, set the following to connect:

• Port: The port used to connect to the server hosting the Oracle database.
• User: The user Id provided for authentication with the Oracle database.
• Password: The password provided for authentication with the Oracle database.
• Service Name: The service name of the Oracle database.

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

Build a Dataset for Oracle Data

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

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. 👁 Connecting to the Domo Service.
   
2. In the DataSet Jobs submenu, click Add New.
3. Name the dataset job (i.e., ODBC Oracle Customers), select ODBC Connection Provider as the transport method, and click through the wizard. 👁 Configuring the DataSet Job.
   
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 OracleOCI Sys) for the System DSN.
7. Click to validate the configuration. 👁 Configuring the Source Settings.
   
8. Below the settings, set the Query to a SQL query:

   SELECT * FROM Customers

   NOTE: By connecting to Oracle data using an ODBC driver, you simply need to know SQL in order to get your data, circumventing the need to know Oracle-specific APIs or protocols.
9. Click preview. 👁 Querying Oracle Data.
   
10. Check over the generated schema, add any transformations, then save and run the dataset job. 👁 Save and Run the Configured DataSet Job (Salesforce is shown).
    

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

Create Data Visualizations

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

1. Navigate to the Data Center. 👁 Accessing the Data Center (Salesforce is shown).
   
2. In the data warehouse, select the ODBC data source and drill down to our new dataset. 👁 Selecting the Oracle Dataset (Salesforce is shown).
   
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.
   👁 Visualizing Oracle Data in Domo (Salesforce is shown).
   

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