Leverage the Active Query Builder SQL interface and .NET data access to create data-driven WinForms and ASP.NET apps backed by Nuclia.

Write standard .NET to expose Nuclia data through an SQL interface: Active Query Builder helps developers write SQL interfaces; the CData ODBC Driver for Nuclia enables standards-based access to Nuclia. This integration uses the Microsoft ADO.NET Provider for ODBC as a bridge between the ODBC Driver and the Active Query Builder objects to build a visual SQL composer.

Connect to Nuclia as an ODBC Data Source

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.

Use SQL to Interact with Nuclia

Follow the steps below to create a WinForms visual query builder.

  1. Open Active Query Builder for .NET WinForms.
  2. In the new Windows Forms project go to the "File" menu and click "Connect..."
  3. Under Database Connections, click "Add..."
  4. Set your desired Connection Name (e.g. CData Nuclia), set Connection Type to "ODBC" and locate your previously configured DSN in the "User/System" DSN dropdown.
  5. Click "OK" to save the new connection.
  6. Back in the Database Connection wizard, select the newly created connection and click "OK."
  7. Click "File" > "New Query" to create a QueryBuilder

You can now build queries visually: Double-click a table in the Columns Pane Area and an entity/relationship diagram is displayed in the Query Building Area. Columns that you select in the diagram are added to the query.
