Programmatic Development using Apex and Visualforce in Lightning Experience (DEX450) Training
Level: Intermediate
Are you a programmer who wants to understand how to customise applications programmatically on the Salesforce platform? In this course, you will learn the core of the Apex programming language and Visualforce markup in order to customise your Salesforce 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 customisations 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 customise your user interface.
