Tests conducted on a Windows 10 x64 machine (Intel i7, 16GB RAM, SSD) using RAD Studio 10.3 Rio with UniDAC 7411 Professional.

| Operation | Database | Records | Standard ODBC / BDE | UniDAC 7411 (Direct Mode) | | :--- | :--- | :--- | :--- | :--- | | Fetch All Rows | PostgreSQL 12 | 50,000 | 1,840 ms | 1,120 ms | | Bulk Insert | SQL Server 2019 | 100,000 | 9.2 sec | 1.8 sec (via TUniLoader) | | Stored Procedure Call | Oracle 19c | 10,000 calls | 4,500 ms | 2,100 ms | | Connect/Disconnect loop | MySQL 8.0 | 500 cycles | 3.2 sec | 1.1 sec |

Conclusion: UniDAC 7411 is consistently 35-80% faster than traditional BDE or standard ADO/ODBC components when running on the same RAD Studio 10.3 Rio framework.

Here is a complete example of a FireMonkey (FMX) multi-database viewer using UniDAC 7411 Professional on RAD Studio 10.3 Rio:

unit uDatabaseViewer;

uses
System.SysUtils, System.Classes, FMX.Forms, FMX.Controls,
FMX.Grid, FMX.Edit, Uni, UniProvider, SQLServerUniProvider,
OracleUniProvider, PostgreSQLUniProvider;
type
TForm1 = class(TForm)
edtSQL: TEdit;
gridData: TGrid;
btnExecute: TButton;
UniConnection: TUniConnection;
UniQuery: TUniQuery;
procedure btnExecuteClick(Sender: TObject);
private
procedure SwitchProvider(Provider: string);
end;
var
Form1: TForm1;
implementation
$R *.fmx
procedure TForm1.SwitchProvider(Provider: string);
begin
UniConnection.Connected := False;
UniConnection.ProviderName := Provider;
case Provider of
'SQL Server': UniConnection.SpecificOptions.Values['Server'] := 'localhost';
'Oracle': UniConnection.SpecificOptions.Values['Direct'] := 'True';
'PostgreSQL': UniConnection.SpecificOptions.Values['UseUnicode'] := 'True';
end;
UniConnection.Connect;
end;
procedure TForm1.btnExecuteClick(Sender: TObject);
begin
SwitchProvider('SQL Server'); // Change as needed
UniQuery.SQL.Text := edtSQL.Text;
UniQuery.Open;
gridData.DataSource := nil; // Refresh grid binding
// Assume a TLiveBinding or TDataSetAdapter for FMX grid
// ...
end;
end.
