Create an SAP BusinessObjects Universe on the CData ODBC Driver for Lakebase

This article shows how to create and publish an SAP BusinessObjects universe on the CData ODBC Driver for Lakebase. You will connect to Lakebase data from the Information Design Tool as well as the Web Intelligence tool.

Connect to Lakebase 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.

• DatabricksInstance: The Databricks instance or server hostname, provided in the format instance-abcdef12-3456-7890-abcd-abcdef123456.database.cloud.databricks.com.
• Server: The host name or IP address of the server hosting the Lakebase database.
• Port (optional): The port of the server hosting the Lakebase database, set to 5432 by default.
• Database (optional): The database to connect to after authenticating to the Lakebase Server, set to the authenticating user's default database by default.

OAuth Client Authentication

To authenicate using OAuth client credentials, you need to configure an OAuth client in your service principal. In short, you need to do the following:

1. Create and configure a new service principal
2. Assign permissions to the service principal
3. Create an OAuth secret for the service principal

For more information, refer to the Setting Up OAuthClient Authentication section in the Help documentation.

OAuth PKCE Authentication

To authenticate using the OAuth code type with PKCE (Proof Key for Code Exchange), set the following properties:

• AuthScheme: OAuthPKCE.
• User: The authenticating user's user ID.

For more information, refer to 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.

Create an ODBC Connection to Lakebase Data

This section shows how to create a connection to the Lakebase ODBC data source in the Information Design Tool. After you create a connection, you can analyze data or create a BusinessObjects universe.

1. Right-click your project and click New -> New Relational Connection.

2. In the wizard that is displayed, enter a name for the connection.

3. Select Generic -> Generic ODBC datasource -> ODBC Drivers and select the DSN.

4. Finish the wizard with the default values for connection pooling and custom parameters.

Analyze Lakebase Data in the Information Design Tool

In the Information Design Tool, you can use both published and local ODBC connections to browse and query data.

1. In the Local Projects view, double-click the connection (the .cnx file) to open the Lakebase data source.

2. On the Show Values tab, you can load table data and enter SQL queries. To view table data, expand the node for the table, right-click the table, and click Show Values. Values will be displayed in the Raw Data tab.

3. On the Analysis tab, you can drag and drop columns onto the axes of a chart.

Publish the Local Connection

To publish the universe to the CMS, you additionally need to publish the connection.

1. In the Local Projects view, right-click the connection and click Publish Connection to a Repository.

2. Enter the host and port of the repository and connection credentials.

3. Select the folder where the connection will be published.

4. In the success dialog that results, click Yes to create a connection shortcut.

Create a Universe on the ODBC Driver for Lakebase

You can follow the steps below to create a universe on the ODBC driver for Lakebase. The universe in this example will be published to a repository, so it uses the published connection created in the previous step.

1. In the Information Design Tool, click File->New Universe.

2. Select your project.

3. Select the option to create the universe on a relational data source.

4. Select the shortcut to the published connection.

5. Enter a name for the Data Foundation.

6. Import tables and columns that you want to access as objects.

7. Enter a name for the Business Layer.

Publish the Universe

You can follow the steps below to publish the universe to the CMS.

1. In the Local Projects view, right-click the business layer and click Publish -> To a Repository.

2. In the Publish Universe dialog, enter any integrity checks before importing.

3. Select or create a folder on the repository where the universe will be published.

Query Lakebase Data in Web Intelligence

You can use the published universe to connect to Lakebase in Web Intelligence.

1. Open Web Intelligence from the BusinessObjects launchpad and create a new document.

2. Select the Universe option for the data source.

3. Select the Lakebase universe. This opens a Query Panel. Drag objects to the Result Objects pane to use them in the query.
