RapidMiner からSQL Server Data にデータ連携

RapidMiner Studio の標準コンポーネントおよびデータソース設定ウィザードでSQL Server data を連携します。

この記事では、CData JDBC driver for SQL Server をRapidMiner のプロセスに簡単に統合する方法を説明します。ここでは、SQL Server にCData JDBC ドライバーを使用して、SQL Server data をRapidMiner のプロセスに転送します。

JDBC データソースとしてRapidMiner のSQL Server に接続

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

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

    Connecting to Microsoft SQL Server

    Connect to Microsoft SQL Server using the following properties:

    • Server: The name of the server running SQL Server.
    • User: The username provided for authentication with SQL Server.
    • Password: The password associated with the authenticating user.
    • Database: The name of the SQL Server database.

    Connecting to Azure SQL Server and Azure Data Warehouse

    You can authenticate to Azure SQL Server or Azure Data Warehouse by setting the following connection properties:

    • Server: The server running Azure. You can find this by logging into the Azure portal and navigating to "SQL databases" (or "SQL data warehouses") -> "Select your database" -> "Overview" -> "Server name."
    • User: The name of the user authenticating to Azure.
    • Password: The password associated with the authenticating user.
    • Database: The name of the database, as seen in the Azure portal on the SQL databases (or SQL warehouses) page.

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

    java -jar cdata.jdbc.sql.jar

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

    A typical connection string is below:

    User=myUser;Password=myPassword;Database=NorthWind;Server=myServer;Port=1433;
  10. Enter your username and password if necessary.

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