3.1. APEX Page Attributes

In the previous chapter, you created pages with the help of wizards built into the APEX development environment. The wizards walked you through the process of specifying values for a variety of parameters. Once you assigned these values, Oracle Application Express used them to generate code which presents and processes your pages.

The code itself is generated with PL/SQL, the Oracle procedural extension language for SQL. You will see, in this and later chapters, that you can add your own PL/SQL code to an APEX page to extend the standard logic, but you need not concern yourself with the actual code that is generated. The APEX environment allows you access to the same parameters you entered through the wizard, and many, many more, which you can use to shape your own applications.

The focus of this book is to get you productively using APEX to create your own applications, rather than giving you a comprehensive description of every possible way you can use every feature within the environment. But you will still have to become familiar with the way you can access those features in the APEX development environment.
