Viewing Nuclia Data in RAD Studio Data Explorer

Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for Nuclia, you gain access to live Nuclia data within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to both retrieve Nuclia data. This article will walk through connecting to Nuclia using the Data Explorer.

Configure a Connection to Nuclia

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

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.

Connecting to Nuclia Data Using Data Explorer

You can create a simple application for displaying Nuclia data by utilizing the CData FireDAC Components for Nuclia and a new VCL Forms Application:

1. Open the Data Explorer in RAD Studio and expand FireDAC.
2. Right-click the ODBC Data Source node in the Data Explorer.
3. Click Add New Connection.
4. Enter a name for the connection.
5. In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for Nuclia.
6. Back in the Data Explorer, expand the views for the connection.

7. Create a new VCL Forms application and drag a view (for example: KnowledgeBox) onto the form.

   
8. Select the KnowledgeBoxView object on the form and set the Active property to true.

9. Right-click on the object, bind visually, and link everything (*) to a new control (TStringGrid).

   

10. Arrange the TStringGrid on the form and run the application to see the KnowledgeBox data.
