Connect to Suadeo Data in RapidMiner

This article shows how you can easily integrate the CData JDBC driver for Suadeo into your processes in RapidMiner. This article uses the CData JDBC Driver for Suadeo to transfer Suadeo data to a process in RapidMiner.

Connect to Suadeo in RapidMiner as a JDBC Data Source

You can follow the procedure below to establish a JDBC connection to Suadeo:

1. Add a new database driver for Suadeo: Click Connections -> Manage Database Drivers.
2. In the resulting wizard, click the Add button and enter a name for the connection.
3. Enter the prefix for the JDBC URL:

   jdbc:suadeo:
   

4. Enter the path to the cdata.jdbc.suadeo.jar file, located in the lib subfolder of the installation directory.
5. Enter the driver class:

   cdata.jdbc.suadeo.SuadeoDriver
   

   
6. Create a new Suadeo connection: Click Connections -> Manage Database Connections.
7. Enter a name for your connection.
8. For Database System, select the Suadeo driver you configured previously.
9. Enter your connection string in the Host box.

   The driver uses the OAuth 2.0 Resource Owner Password Credentials (ROPC) grant to authenticate to Suadeo. Authentication occurs directly using your credentials; there is no browser-based authorization flow or refresh token.

   Set the following connection properties:

   • URL: The base URL of your Suadeo instance.
   • User: Your Suadeo username.
   • Password: Your Suadeo password.
   • AuthenticationName: The name identifier for the authentication configuration in your Suadeo instance. Different authentication names can be configured for different environments or use cases.

   When you connect, the driver sends your credentials to the Suadeo OAuth token endpoint, receives an access token, and uses it for all subsequent requests. A new access token is obtained automatically when needed during the session.

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the Suadeo JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

   java -jar cdata.jdbc.suadeo.jar
   

   Fill in the connection properties and copy the connection string to the clipboard.

   

   A typical connection string is below:

   URL=https://mysuadeoinstance;User=username;Password=password;AuthenticationName=your_auth_name;
   

10. Enter your username and password if necessary.

You can now use your Suadeo connection with the various RapidMiner operators in your process. To retrieve Suadeo data, drag the Retrieve operator from the Operators view. 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 Suadeo data.
