  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 Azure Data Catalog.
  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: Tables) onto the form.

  8. Select the TablesView 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 Tables data.
