5. Enter the driver class:

   cdata.jdbc.wavefinancial.WaveFinancialDriver
   

   👁 The JDBC driver configuration. (Salesforce is shown.)
   
6. Create a new Wave Financial connection: Click Connections -> Manage Database Connections.
7. Enter a name for your connection.
8. For Database System, select the Wave Financial driver you configured previously.
9. Enter your connection string in the Host box.

   A typical connection string is below:

   InitiateOAuth=GETANDREFRESH;
   

10. Enter your username and password if necessary. 👁 The connection to the JDBC data source. (Salesforce is shown.)
    

You can now use your Wave Financial connection with the various RapidMiner operators in your process. To retrieve Wave Financial data, drag the Retrieve operator from the Operators view. 👁 A Retrieve operation to select data. (Salesforce is shown.)
With the Retrieve operator selected, you can then define which table to retrieve in the Parameters view by clicking the folder icon next to the "repository entry." In the resulting Repository Browser, you can expand your connection node to select the desired example set.

Finally, wire the output to the Retrieve process to a result, and run the process to see the Wave Financial data.
