RapidMiner からBtrieve 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Btrieve data を連携します。

この記事では、CData JDBC driver for Btrieve 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、Btrieve にCData JDBC ドライバーを使用して、Btrieve 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Btrieve に接続

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

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

    The PSQL v13 client will need to be installed on the same machine as the driver. To connect, set the User, Password, Server, and Database properties.

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

    java -jar cdata.jdbc.btrieve.jar

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

    A typical connection string is below:

    User=myuser;Password=mypassword;Server=myserver;Database=mydatabase;
  10. Enter your username and password if necessary.

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