Connect to Cvent Data in RapidMiner

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

Connect to Cvent in RapidMiner as a JDBC Data Source

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

1. Add a new database driver for Cvent: 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:cvent:
4. Enter the path to the cdata.jdbc.cvent.jar file, located in the lib subfolder of the installation directory.
5. Enter the driver class: cdata.jdbc.cvent.CventDriver
6. Create a new Cvent connection: Click Connections -> Manage Database Connections.
7. Enter a name for your connection.
8. For Database System, select the Cvent driver you configured previously.
9. Enter your connection string in the Host box.

   Before you can authenticate to Cvent, you must create a workspace and an OAuth application.

   Creating a Workspace

   To create a workspace:

   1. Sign into Cvent and navigate to App Switcher (the blue button in the upper right corner of the page) >> Admin.
   2. In the Admin menu, navigate to Integrations >> REST API.
   3. A new tab launches for Developer Management. Click on Manage API Access in the new tab.
   4. Create a Workspace and name it. Select the scopes you would like your developers to have access to. Scopes control what data domains the developer can access.
      • Choose All to allow developers to choose any scope, and any future scopes added to the REST API.
      • Choose Custom to limit the scopes developers can choose for their OAuth apps to selected scopes. To access all tables exposed by the driver, you need to set the following scopes:

        event/attendees:read	event/attendees:write	event/contacts:read
        event/contacts:write	event/custom-fields:read	event/custom-fields:write
        event/events:read	event/events:write	event/sessions:delete
        event/sessions:read	event/sessions:write	event/speakers:delete
        event/speakers:read	event/speakers:write	budget/budget-items:read
        budget/budget-items:write	exhibitor/exhibitors:read	exhibitor/exhibitors:write
        survey/surveys:read	survey/surveys:write

   Creating an OAuth Application

   After you have set up a Workspace and invited them, developers can sign up and create a custom OAuth app. See the Creating a Custom OAuth Application section in the Help documentation for more information.

   Connecting to Cvent

   After creating an OAuth application, set the following connection properties to connect to Cvent:

   • InitiateOAuth: GETANDREFRESH. Used to automatically get and refresh the OAuthAccessToken.
   • OAuthClientId: The Client ID associated with the OAuth application. You can find this on the Applications page in the Cvent Developer Portal.
   • OAuthClientSecret: The Client secret associated with the OAuth application. You can find this on the Applications page in the Cvent Developer Portal.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.cvent.jar

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

   A typical connection string is below:

   OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;InitiateOAuth=GETANDREFRESH
10. Enter your username and password if necessary.

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