Salesforce Programmatic Development Using Apex and Visualforce (DEX450)

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.

Create and modify objects using the declarative interface

Write business logic customizations using Apex triggers and classes. Those customizations will use SOQL and DML.
Design programmatic solutions that take advantage of declarative customizations
Describe how your trigger code works within the basics of the Save Order of Execution
Describe some of the fundamental aspects of designingprograms on a multi-tenant platform
Write Visualforce markup and code to customize the user interface
Use the built-in testing framework to test Apex and Visualforces
