Connect to Reckon Data in RapidMiner

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

Connect to Reckon in RapidMiner as a JDBC Data Source

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

1. Add a new database driver for Reckon: 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:reckon:
   

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

   cdata.jdbc.reckon.ReckonDriver
   

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

   When you are connecting to a local Reckon instance, you do not need to set any connection properties.

   Requests to Reckon are made through the Remote Connector. The Remote Connector runs on the same machine as Reckon and accepts connections through a lightweight, embedded Web server. The server supports SSL/TLS, enabling users to connect securely from remote machines.

   The first time you connect to your company file, authorize the Remote Connector with Reckon. See the "Getting Started" chapter 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 Reckon JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

   java -jar cdata.jdbc.reckon.jar
   

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

   A typical connection string is below:

   User=RCUser;Password=RCUserPassword;URL=http://remotehost:8166;
   

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

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