Programmatic Development Using Apex and Visualforce in Lightning Exper DEX-450

PT26085
Summary
Are you a programmer who wants to understand how to customize applications programmatically on the Force.com platform? In this course, you will learn the core of the Apex programming language and Visualforce markup in order to customize your Force.com applications. You will get hands-on experience building data objects (sObjects) and programmatically retrieving, manipulating, and storing the data associated with those objects. You will write custom logic using Apex triggers and classes, and test that logic using the built-in testing framework. You will explore how Apex code interacts with declarative customizations on the platform, and the nuances of working on a multi-tenant platform. You’ll then examine common techniques for designing solutions in Apex. These activities will culminate in an exercise building a complex trigger that takes advantage of the declarative aspects of the platform. You will get hands-on experience writing Visualforce pages to customize your user interface and Visualforce controllers (in Apex) to modify the controller behavior behind the interface. You’ll also explore design techniques and the built-in testing framework around Visualforce.
