About Built-in Subprograms
To make writing code easier, Oracle Forms includes over 150 built-in procedures and
functions that perform a variety of standard application functions, including navigation,
commit processing, and setting and getting object properties programmatically.
In addition to the Oracle Forms built-in subprograms, you can also code your own user-
named procedures, functions, or packages. These objects, collectively known as program
units, can be defined in forms, menus, or library modules. Once you have defined a
procedure or function, you can call it in triggers, menu item commands, and other program
units.
About Application Partitioning
PL/SQL is the language used for both client-side Oracle Forms applications and server-side
database triggers and stored procedures, and there is a PL/SQL engine in both Oracle Forms
Runform and the Oracle7 Server. This means that you can take advantage of application
partitioning to execute application code on either the client or the server. Application
partitioning allows you to optimize performance and resource usage by storing and executing
procedures either locally or at the server, whichever makes the most sense for your particular
application and configuration.
When you work in the Oracle Forms Designer, you can use the integrated stored procedure
and database trigger editors to code server-side application logic at the same time you
develop your client-side applications.
To make application-partitioning even easier, Oracle Forms allows you to drag-and-drop
procedures between your application and the server in one simple mouse operation. With
drag-and-drop partitioning, you can quickly move procedures between your application and
the server, without having to change any of the code in your application.
