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

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

Connect to AlloyDB 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.

The following connection properties are usually required in order to connect to AlloyDB.

• Server: The host name or IP of the server hosting the AlloyDB database.
• User: The user which will be used to authenticate with the AlloyDB server.
• Password: The password which will be used to authenticate with the AlloyDB server.

You can also optionally set the following:

• Database: The database to connect to when connecting to the AlloyDB Server. If this is not set, the user's default database will be used.
• Port: The port of the server hosting the AlloyDB database. This property is set to 5432 by default.

Authenticating with Standard Authentication

Standard authentication (using the user/password combination supplied earlier) is the default form of authentication.

No further action is required to leverage Standard Authentication to connect.

Authenticating with pg_hba.conf Auth Schemes

There are additional methods of authentication available which must be enabled in the pg_hba.conf file on the AlloyDB server.

Find instructions about authentication setup on the AlloyDB Server here.

Authenticating with MD5 Authentication

This authentication method must be enabled by setting the auth-method in the pg_hba.conf file to md5.

Authenticating with SASL Authentication

This authentication method must be enabled by setting the auth-method in the pg_hba.conf file to scram-sha-256.

Authenticating with Kerberos

The authentication with Kerberos is initiated by AlloyDB Server when the ∏ is trying to connect to it. You should set up Kerberos on the AlloyDB Server to activate this authentication method. Once you have Kerberos authentication set up on the AlloyDB Server, see the Kerberos section of the help documentation for details on how to authenticate with Kerberos.

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

Build a Dataset for AlloyDB Data

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

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

Create Data Visualizations

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