Viewing Twitter Data in RAD Studio Data Explorer

How to view Twitter data in RAD Studio Data Explorer using the CData FireDAC Components for Twitter.

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

Connecting to Twitter Data Using Data Explorer

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

  1. Open the Data Explorer in RAD Studio and expand FireDAC.
  2. Right-click on CData Twitter Data Source and click Add New Connection.

  3. Name the connection.
  4. Fill in the necessary connection parameters and click OK.

    All tables require authentication. You can connect using your User and Password or OAuth. To authenticate using OAuth, you can use the embedded OAuthClientId, OAuthClientSecret, and CallbackURL or you can register an app to obtain your own.

    If you intend to communicate with Twitter only as the currently authenticated user, then you can obtain the OAuthAccessToken and OAuthAccessTokenSecret directly by registering an app.

    See the Getting Started chapter in the help documentation for a guide to using OAuth.

  5. Back in the Data Explorer, expand the tables for the connection.
  6. Create a new VCL Forms application and drag a table (for example: Tweets) onto the form.

  7. Select the TweetsTable object on the form and set the Active property to true.
  8. Right-click on the object, bind visually, and link everything (*) to a new control (TStringGrid).

  9. Arrange the TStringGrid on the form and run the application to see the Tweets data.
