RapidMiner からMySQL 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MySQL data を連携します。

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

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

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

    The Server and Port properties must be set to a MySQL server. If IntegratedSecurity is set to false, then User and Password must be set to valid user credentials. Optionally, Database can be set to connect to a specific database. If not set, tables from all databases will be returned.

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

    java -jar cdata.jdbc.mysql.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=3306;
  10. Enter your username and password if necessary.

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