Connect to Azure DevOps Data in RapidMiner

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

Connect to Azure DevOps in RapidMiner as a JDBC Data Source

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

1. Add a new database driver for Azure DevOps: 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:azuredevops:
4. Enter the path to the cdata.jdbc.azuredevops.jar file, located in the lib subfolder of the installation directory.
5. Enter the driver class: cdata.jdbc.azuredevops.AzureDevOpsDriver
6. Create a new Azure DevOps connection: Click Connections -> Manage Database Connections.
7. Enter a name for your connection.
8. For Database System, select the Azure DevOps driver you configured previously.
9. Enter your connection string in the Host box. You can connect to your Azure DevOps account by providing the Organization and PersonalAccessToken.

   Obtaining a Personal Access Token

   A PersonalAccessToken is necessary for account authentication.

   To generate one, log in to your Azure DevOps Organization account and navigate to Profile -> Personal Access Tokens -> New Token. The generated token will be displayed.

   If you wish to authenticate to Azure DevOps using OAuth refer to the online Help documentation for an authentication guide.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.azuredevops.jar

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

   A typical connection string is below:

   AuthScheme=Basic;Organization=MyAzureDevOpsOrganization;ProjectId=MyProjectId;PersonalAccessToken=MyPAT;InitiateOAuth=GETANDREFRESH
10. Enter your username and password if necessary.

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