This document discusses automatically converting Oracle Forms code to Delphi code. It notes some issues with running Oracle Forms applications using Java applets, including performance problems and lack of support in modern browsers. It then describes how converting the code to Delphi allows running it as a native Windows/Mac/iOS application or as a web application using HTML5. This provides benefits like faster performance, support on all browsers, and the ability to reuse the same code and database on different platforms. It also explains the conversion process aims to maintain the structure and naming of the original PL/SQL code.

• Deployment on every PC with Java installed
• Expensive Oracle Application Server license fee
• Performance problem
• Modern browsers stopped offering full support for the Netscape Plugin API, therefore they can no
longer run Java applets natively

• Faster application
• Supported by all modern browsers
• Same database
• 32/64 bit
• Supports all Oracle DB versions

Database Tier
• Very fast executable (native 32/64 bit!)
• Same source code for Web version/Win32/Win64
• Low memory usage
• Low CPU usage
• Supports all oracle database versions

5. Before: Applet Java Forms

6. After: Windows 8 - 64 bit

7. After: WEB HTML5 !!!!

8. Code Reuse
100% of the PL/SQL code is converted in Delphi with the structure and variable
names.
Procedure Check_Package_Failure IS
BEGIN
IF NOT ( Form_Success ) THEN
RAISE Form_Trigger_Failure;
END IF;
END;
procedure Check_Package_Failure;
begin
if (not Form_Success) then
begin
raise Ex_OF_Form_Trigger_Failure.create;
end;
end;
After translation
Original code
syntax and semantic very
close to PL/SQL code
