What Is a Page?

A page is the basic building block of an application. When you build an application in Application Builder, you create pages that contain user interface elements, such as tabs, lists, buttons, items, and regions.

You add controls to a page on the Page Definition.

To view the Page Definition of an existing page:

Navigate to the Database Home Page.
Click the Application Builder icon.
Select an application.
Select a page.

The Page Definition appears and is divided into three main sections:
- Page Rendering lists user interface controls and logic that is executed when the page is rendered. See "About Page Rendering Controls".
- Page Processing lists logic controls (such as computations and processes) that are evaluated and executed when the page is processed. See "About Page Processing Controls".
- Shared Components lists common components that can display or be applied on every page within an application. See "About Shared Components".
