What you'll learn

  • Write Apex that is bulk-safe because it was designed that way
  • Use SOQL, SOSL and DML inside the limits rather than against them
  • Reason about triggers and the order of execution in a busy org
  • Fail well: handle errors so the transaction does the right thing
  • Write tests that prove behaviour, and ship code through a real pipeline

  • A free Developer Edition org

Description

Almost every Apex course teaches the language as though the platform were incidental — variables, loops, collections, classes, and then, forty minutes from the end, governor limits as an annoyance. That produces developers whose code works in the Developer Console and fails in production.

This course inverts it. The limit is the design constraint, so bulk patterns, SOQL and DML discipline, the order of execution, testing and failure are taught as the subject rather than the epilogue. It covers the Salesforce Certified Platform Developer blueprint, and eight other courses on this shelf name it as their prerequisite — nothing else here carries that much weight behind it.

Who this course is for

  • Administrators becoming developers, and programmers new to the Salesforce platform.
