RapidMiner からAlfresco Data にデータ連携

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

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

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

   To connect to Alfresco, the following connection properties must be supplied: User, Password, and InstanceUrl. User and Password correspond to the login credentials that you use to access Alfresco in a web browser. InstanceUrl corresponds to the Alfresco instance you will be querying. For instance, if you expect your queries to hit https://search-demo.dev.alfresco.me/alfresco/api/-default-/public/search/versions/1/sql, you should supply search-demo.dev.alfresco.me for InstanceUrl.

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

   java -jar cdata.jdbc.alfresco.jar

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

   

   A typical connection string is below:

   User=MyUsername; Password=MyPassword; Format=Solr; InstanceUrl=api-explorer.alfresco.com;
10. Enter your username and password if necessary.

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