Apex Design Patterns — Part 2| Behavioral Patterns: Strategy, Observer & Command

In Part 1, we covered how objects get created.    • Apex Design Patterns – Part 1: Foundations...   In Part 2, we're answering a different question — how do objects communicate? Three behavioral patterns that will change the way you write triggers, services, and business logic in Salesforce Apex: Strategy — Replace growing if-else chains with composable, swappable algorithms Observer — Keep your triggers clean by decoupling the event from its reactions Command — Turn actions into objects so you can log, undo, queue, and replay them Each pattern includes a real-world analogy, an Apex code walkthrough, and a live demo in a Salesforce org.
