Viewing Perigon 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 Perigon, you gain access to live Perigon data within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to both retrieve Perigon data. This article will walk through connecting to Perigon using the Data Explorer.

Configure a Connection to Perigon

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

To use the Perigon API, you need to obtain an API key from your Perigon account. Navigate to the Perigon dashboard and generate an API key from your account settings.

After setting the following connection properties, you are ready to connect:

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

Example connection string:

Profile=C:\profiles\Perigon.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_api_key"

Available Tables

The Perigon profile provides access to the following tables:

• Articles - News articles retrieved from the Perigon news intelligence API
• Headlines - Story clusters grouping related headline articles
• Sources - News sources tracked by the Perigon news intelligence API
• Journalists - Journalist profiles tracked by the Perigon news intelligence API

Connecting to Perigon Data Using Data Explorer

You can create a simple application for displaying Perigon data by utilizing the CData FireDAC Components for Perigon 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 Perigon.
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: Articles) onto the form.

   
8. Select the ArticlesView 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 Articles data.
