Oracle Application Express 23 (APEX)

This Oracle Application Express 23 (APEX) course introduces the delegate to Oracle's Application Express version 23 software. It is designed to give delegates practical experience in using Application Express version 23, also known as Apex, for building web-based applications for an Oracle database.

In version 23, template components are introduced, a new type of developer-defined plug-in. These support template directives which provide for both conditional execution and looping. There are several seeded template components as well, including avatars and media lists.

Support is provided for PWA Push Notifications.

There is new functionality for monitoring execution of background processes, and the creation of execution chains for processes, whether running in foreground or background mode.

Further enhancements have been made to the developer interface for greater ease of use.

Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.
