RapidMiner から 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 data を連携します。

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

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

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

    Google uses the OAuth authentication standard. To access Google APIs on behalf on individual users, you can use the embedded credentials or you can register your own OAuth app.

    OAuth also enables you to use a service account to connect on behalf of users in a Google Apps domain. To authenticate with a service account, you will need to register an application to obtain the OAuth JWT values.

    In addition to the OAuth values, to access Google data you will need the Email of the Google account. See the "Getting Started" chapter in the help documentation for a guide to using OAuth.

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

    java -jar cdata.jdbc.googleapps.jar

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

    A typical connection string is below:

    OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost;Email=myemail@gmail.com;InitiateOAuth=GETANDREFRESH
  10. Enter your username and password if necessary.

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