Feed Hugging Face Data into FineReport

The CData JDBC Driver for Hugging Face fully implements the JDBC standard and can provide Hugging Face data connectivity to a wide variety of BI, reporting, and ETL tools and custom applications. In this article, we explain how to set Hugging Face data as JDBC data source in FineReport and view Hugging Face data as a table in the Report Designer.

Set Up a JDBC Data Source of Hugging Face Data

Follow the instruction below to set Hugging Face data as a FineReport database connection.

1. Copy the cdata.jdbc.api.jar file from the lib folder in the CData JDBC Driver for Hugging Face installation directory to the lib folder of the FineReport installation directory. You will need to copy the cdata.jdbc.api.lic file as well.
2. From the Server tab, select Define Data Connection, click to add a new connection, and click JDBC.

Next we will set up the data connection definition in the window.

1. Database: Others
2. JDBC Driver: cdata.jdbc.api.APIDriver
3. URL: A standard JDBC connection string using semicolon-separated connection properties.

   HuggingFace Hub uses token-based authentication to enable access to its API. The API provides access to machine learning models, datasets, spaces, papers, and other resources on the HuggingFace Hub platform.

   Using API Key Authentication

   To authenticate to HuggingFace Hub, you will need to provide an API Key (Access Token). To obtain your access token:

   1. Log in to your HuggingFace account at https://huggingface.co
   2. Navigate to Settings > Access Tokens
   3. Click "New token" to create a new access token
   4. Select the appropriate permissions (read or write)
   5. Copy the token value

   After obtaining your access token, set the following connection properties:

   • AuthScheme: Set this to APIKey.
   • APIKey: Set this to your HuggingFace access token.

   Example connection string

   Profile=C:\profiles\HuggingFace.apip;ProfileSettings='APIKey=hf_xxxxxxxxxxxxxxxxxxxx';
   

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the Hugging Face 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.

   

   When you configure the JDBC URL, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

   A typical JDBC URL is below:

       jdbc:api:Profile=C:\profiles\HuggingFace.apip;ProfileSettings='APIKey=hf_xxxxxxxxxxxxxxxxxxxx';
     


4. Click Connection pool attributes and set Test before getting connections to No.

Click Test connection to ensure you have configured the connection properly. With the connection to Hugging Face set up, you can use it as FineReport data source.

Select Hugging Face Data in the Report Designer.

1. Click to add a new template data set and select DB query to open the database query window.

2. Choose the JDBC connection that you created from the dropdown list.
3. The Hugging Face entities will appear as tables on the left pane.
4. Write a SELECT statement for the Hugging Face data tables and columns that you want to load.

5. Click preview and data is shown as table.

With these simple steps, Hugging Face can be used as a JDBC data source in FineReport.
