Connect to Qualaroo Data in RapidMiner

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

Connect to Qualaroo in RapidMiner as a JDBC Data Source

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

1. Add a new database driver for Qualaroo: 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:api:
   

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

   cdata.jdbc.api.APIDriver
   

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

   Qualaroo uses HTTP Basic Authentication to control access to the API. You will need your API Key and API Secret, which can be found under Account Details > Reporting API in the Qualaroo dashboard.

   Using Basic Authentication

   After setting the following connection properties, you are ready to connect:

   • AuthScheme: Set this to Basic.
   • User: Set this to your Qualaroo API Key.
   • Password: Set this to your Qualaroo API Secret.

   Example connection string:

   Profile=C:\profiles\Qualaroo.apip;AuthScheme=Basic;User=your_api_key;Password=your_api_secret;
   

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.api.jar
   

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

   

   A typical connection string is below:

   Profile=C:\profiles\Qualaroo.apip;AuthScheme=Basic;User=your_api_key;Password=your_api_secret;
   

10. Enter your username and password if necessary.

You can now use your Qualaroo connection with the various RapidMiner operators in your process. To retrieve Qualaroo 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 Qualaroo data.
