Connecting from RAD Studio

The CData FireDAC Components for Presto implement the standard FireDAC classes and integrate Presto into RAD Studio wizards. You can access the components from the RAD Studio Tool Palette and use the components alongside standard FireDAC classes like TFDQuery, TFDManager, and TFDConnection.
