Connect to Google Calendar Data in RapidMiner

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

Connect to Google Calendar in RapidMiner as a JDBC Data Source

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

1. Add a new database driver for Google Calendar: 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:googlecalendar:
   

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

   cdata.jdbc.googlecalendar.GoogleCalendarDriver
   

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

   You can connect to Google APIs on behalf of individual users or on behalf of a domain. Google uses the OAuth authentication standard. See the "Getting Started" section of the help documentation for a guide.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.googlecalendar.jar
   

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

   A typical connection string is below:

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

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