Course Description

This course is designed for Salesforce administrators who would like to learn the basics of implementing business logic using Apex, the primary programming language of the Salesforce platform. First, you’ll learn how to read Apex code and then you’ll gradually increase your programming skills from writing single debugging statements to programming multiple, multi-line blocks of code.
