How to Connect DBeaver to Nuclia via a JDBC Driver

The CData API Driver for JDBC implements JDBC standards that enable third-party tools to interoperate, from wizards in IDEs to business intelligence tools. This article shows how to connect to Nuclia data with wizards in DBeaver and browse data in the DBeaver GUI.

Create a JDBC Data Source for Nuclia Data

Follow the steps below to load the driver JAR in DBeaver.

1. Open the DBeaver application and, in the "Database" menu, select the "Driver Manager" option. Click "New" to open the "Create new driver" form.
2. In the Settings tab:
   • Set Driver Name to a user-friendly name for the driver (e.g. CData API Driver for JDBC).
   • Set Class Name to the class name for the JDBC driver: cdata.jdbc.api.APIDriver.
   • Set URL Template to jdbc:api:.
   
3. In the Libraries tab, click "Add File," navigate to the "lib" folder in the installation directory (C:\Program Files\CData[product_name] XXXX\) and select the JAR file (cdata.jdbc.API.jar).

Create a Connection to Nuclia Data

Follow the steps below to add credentials and other required connection properties.

1. In the "Database" menu, click "New Database Connection."
2. In the "Connect to a database" wizard that results, select the driver you just created (e.g. CData API Driver for JDBC) and click "Next >."
3. On the Main tab of the configuration wizard, set the JDBC URL, using the required connection properties:

   Using API Key Authentication

   Nuclia uses API key authentication for accessing Knowledge Box data. To obtain an API key:

   1. Log in to the Nuclia Cloud Dashboard at https://nuclia.cloud
   2. Navigate to your Knowledge Box settings
   3. Go to the Service Accounts section
   4. Create a new service account or copy an existing API key

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

   • AuthScheme: Set this to APIKey.
   • APIKey: Set this to your Nuclia service account API key.
   • KbId: Set this to your Knowledge Box UUID.
   • Zone: Set this to your Nuclia deployment zone (e.g., aws-us-east-2-1).

   Example Connection String

   Profile=C:\profiles\Nuclia.apip;AuthScheme=APIKey;APIKey=your_service_account_key;KbId=your_kb_uuid;Zone=aws-us-east-2-1;
   

   Connecting to Nuclia

   Once the authentication is configured, you can connect to Nuclia and query data from any of the available tables such as Resources, KnowledgeBox, LabelSets, and ProcessingStatus.

   Built-in Connection String Designer

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

   

   Below is a typical connection string:

   jdbc:api:Profile=C:\profiles\Nuclia.apip;AuthScheme=APIKey;APIKey=your_service_account_key;KbId=your_kb_uuid;Zone=aws-us-east-2-1;
   

   
4. Click "Test Connection ..." to ensure you have configured the connection properly.
5. Click "Finish."

Query Nuclia Data

You can now query information from the tables exposed by the connection: Right-click a Table and then click View Table. The data is available on the Data tab.
