Connect to Azure Analysis Services Data in RapidMiner

Integrate Azure Analysis Services data with standard components and data source configuration wizards in RapidMiner Studio.

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

Connect to Azure Analysis Services in RapidMiner as a JDBC Data Source

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

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

    To connect to Azure Analysis Services, set the Url property to a valid server, for instance, asazure://southcentralus.asazure.windows.net/server, in addition to authenticating. Optionally, set Database to distinguish which Azure database on the server to connect to.

    Azure Analysis Services uses the OAuth authentication standard. OAuth requires the authenticating user to interact with Azure Analysis Services using the browser. You can connect without setting any connection properties for your user credentials. See the Help documentation for more information.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.aas.jar

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

    A typical connection string is below:

    URL=asazure://REGION.asazure.windows.net/server;InitiateOAuth=GETANDREFRESH
  10. Enter your username and password if necessary.

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