Programmatic Development Using Apex & Visualforce

Are you a programmer who wants to understand how to customize applications programmatically
on the platform? In this course, you will learn the core of the Apex programming
language and Visualforce markup in order to customize your 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.

This course is designed for programmatic developers who are new to the platform,
who need to be able to write programmatic customizations to both the business logic and user
interface layers using Apex and 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
