What Is Application Builder?

You use the Application Builder component of Oracle Application Express to build your application. Through wizards or your direct input, you can assemble an HTML interface (or application) on top of database objects such as tables and procedures. Each application is a collection of linked pages using tabs, buttons, or hypertext links.

A page is the basic building block of an application. Pages also contain user interface elements such as tabs, lists, buttons, items, and regions. To see the definition of each page belonging to your application, you use the Page Definition page.

The Page Definition contains three main areas:

• Page Rendering lists user interface controls and logic that are executed when a page is rendered. Page rendering is the process of generating a page from the database.

• Page Processing lists logic controls (such as computations and processes) that are evaluated and executed when the page is processed.

• Shared Components lists components used by the current page that can also be referenced by other pages within your application.
