Connect to Deepgram Data in RapidMiner

This article shows how you can easily integrate the CData JDBC driver for Deepgram into your processes in RapidMiner. This article uses the CData JDBC Driver for Deepgram to transfer Deepgram data to a process in RapidMiner.

Connect to Deepgram in RapidMiner as a JDBC Data Source

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

1. Add a new database driver for Deepgram: 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:api:
   

4. Enter the path to the cdata.jdbc.api.jar file, located in the lib subfolder of the installation directory.
5. Enter the driver class:

   
   cdata.jdbc.api.APIDriver
   

   
6. Create a new Deepgram connection: Click Connections -> Manage Database Connections.
7. Enter a name for your connection.
8. For Database System, select the Deepgram driver you configured previously.
9. Enter your connection string in the Host box.

   Start by setting the Profile connection property to the location of the Deepgram Profile on disk (e.g. C:\profiles\Deepgram.apip). Next, set the ProfileSettings connection property to the connection string for Deepgram (see below).

   Deepgram API Profile Settings

   Deepgram uses API key authentication for all endpoints. API keys are scoped to a project and carry permission scopes (member, administrator, or owner). Create and manage API keys in the Deepgram console.

   After obtaining your API key, set the following connection properties:

   • AuthScheme: Set this to APIKey.
   • APIKey: Set this to your Deepgram API key.

   Built-in Connection String Designer

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

   
   java -jar cdata.jdbc.api.jar
   

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

   

   A typical connection string is below:

   
   Profile=C:\profiles\Deepgram.apip;AuthScheme=APIKey;ProfileSettings='APIKey=YOUR_DEEPGRAM_API_KEY';
   

10. Enter your username and password if necessary.

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